I live in a very rural area and have to use DirecPC. I thought about
the cell phone thing but again the rural area thing is going to bite
you because you may not have much of a signal for the cell phone to
bind enough channels for broadband access. I used to use DirectPC with
a land line but then I put security camers and needed 24 hour access so
I upgraded to two way access.
Download is very fast, faster than our T3 at work. Upload seems very
slow and you can't play online games because of latency. See my live
camera feed at and it will give you an idea of the upload speed.
