Actually, I was a bit off... 8 megs would give us 8x64 seconds of buffer ~ around 8:32 of buffer time. Perhaps that could be the max setting, but I think in my case, I'd love to see at least a 1 or 2 meg buffer option.

This would be so great! It would help alot when jumping from 3G to Wifi if we had say a 8 megabyte buffer... that would give us 64 seconds to jump netoworks in most cases :D
