Cory, I'm on a 100mbps set of boxes at
www.serverprovider.com and doing nearly the identical thing you seem to be after.
Very happy, can't stress that enough, they handle my 10MB movie files on paid Hun/Worldsex/SD links no problem, 500kb/s download speed.
Hitup Sami @ ICQ 311-848-143 and talk with him about any setup you need.
