This is an interesting application. I'll admit that I pretty much ignored the original version since it didn't really do much, but this new version is actually very useful. I'm liking the idea of letting the PC do the gruntwork and letting the DS just show an image of the output.
I just have a question though. When I scroll down and it pauses, looking at my task manager it appears that most of the time spent before I regain control is taken up by my computer rendering the next part of the page, with the transmission part afterwards being relatively fast. Would it be possible to add an option to the server to make it constantly render the rest of the page during idle time? This wouldn't help if you're just trying to scroll to the bottom of the page as fast as possible right after loading it, but it would help for pages where you read content at the top of the page for a while before scrolling down.
