Is it possible to still receive SpotPass data? Can you inject the data on a 3DS?

So first of all, what exactly was SpotPass? Was it just extra game data?

Second, if the data has been dumped, as on the "SpotPass Archival Project", where can it be downloaded?

Third, can this data be sent/transmitted to 3DS consoles again? Similar to how the DS Download Stations work? (Yes, I know these are VERY different, but still...)

Thank you! So sorry if this is such a 'novice' question, I'm just wanting some answers!

StreetPass goes a bit like this:
  1. Some title has registered with the console for StreetPass, this is called a "box" (see CecBoxTool or the official registered software list in data management), this is stored somewhere in ctrnand
  2. Console is in 3DS mode, so the 3DS kernel (Native-Firm) is running
  3. Console has wifi on but is not connected to an access point or directly to another console (I think it will disconnect in standby mode every now and then, but it always works better away from registered networks)
  4. CEC driver ("chance encounter communication" - a pretty literal translation of the Japanese for StreetPass "surechigai" which actually dates back to DS games with that feature like ACWW) advertises the console's presence and hopefully another nearby will connect
  5. Boxes are compared according to box ID (a bit like TitleID but with allowances for cross-title communication like Pokemon X+Y) and data is exchanged according to instructions from the title (USUALLY you can think of it like business cards, there's a finite stack of potentially different things that can be given away and they go into a finite-sized wallet)
  6. You notice that happened because you get a green dot on involved titles
  7. Involved titles get run and at some time at their discretion (many do so at launch but for example in Pokemon X/Y you have to go to the holo launcher manually), the contents of the box are collected and the outgoing stack refilled, what happens after this is at the complete discretion of the title and the console/OS doesn't care anymore
SpotPass goes a bit like this:
  1. Some title has registered with the console for SpotPass, this is called a "task" (see BossLotCheckTool, there's no official centralized GUI for retards and/or hackers (as Nintendo qualifies all of their customers)), this is stored on the SD as "Boss extdata" (which the official settings conflate with regular extdata) and you can access it with a save manager that supports it like a 2016 version of JKSV - see https://gbatemp.net/download/streetpass-mii-plaza-eur-most-puzzles.36038/ for an example
  2. Console is in 3DS mode, so the 3DS kernel (Native-Firm) is running
  3. Console has wifi on and is online
  4. BOSS driver fires and performs the tasks
  5. Tasks are tied to a title as above, data is exchanged mainly via HTTP requests according to instructions from the title (ie Mii Plaza downloads expansion puzzles, HOME sends Analytic$$$ and downloads Advertisement$$$, etc), I'm not sure if there's an absolute size limit but there may be one by Nintendo standards
  6. You notice that happened because you get a blue dot on involved titles (you often don't get a notification, unlike those for StreetPass which are generated by the OS)
  7. Involved titles get run and at some time at their discretion: received data may be transferred to the main save/extdata or it might not, and yup, what happens after this is at the complete discretion of the title and the console/OS doesn't care anymore
So:

Largely so, but it could be "anything", including plain marketing (eShop notifications)
Second, if the data has been dumped, as on the "SpotPass Archival Project", where can it be downloaded?
Has it? :) :(
When I dumped that puzzle set because it included a limited edition one, it seemed that nobody else posted anything like that before (= a last-minute rush likely means most of the period-accurate stuff will be missed), and besides, Mii Plaza is one of the titles that have SpotPass-provided addons as a standalone file that stays in Boss extdata, most others don't work that way (= may or may not be friendly to a simple file copy job)
Third, can this data be sent/transmitted to 3DS consoles again? Similar to how the DS Download Stations work? (Yes, I know these are VERY different, but still...)
Yeah, not in that way :)
For those where you can't just paste the already downloaded file in (actually, for every SpotPass title), it would be theoretically possible to have some homebrew that messes with the task data to have it contact some other server (possibly combined with the NoSSL patch)
