Gaming Utilizing two connections for simultaneous downloads?

[wchill]

I have two Internet connections available to me:
3mbit AT&T U-Verse VDSL connection
12mbit Verizon 4G LTE connection

I need to download many large files from sites like Rapidshare, Megaupload, etc. and would thus like to utilize both connections for downloading files.
What I mean by this is that I start a download on one connection, then start a download on another connection at the same time (which should be possible given that the IP addresses each service would see are different).

Any way of accomplishing this without reboots? I have tried adding/deleting routes and that has not helped.

Perhaps using a VM and setting the VM to use one of the specific connections? Not sure on the exact steps you'd take though.

I thought about this too. However, this means that torrents will only go through one connection. :/

The best idea I have is to use multiple computers/laptops. Use one connection for one and the other for the other.
