I would go to a realtive who had dialup internet and offer to pay the difference for broadband. Then, build a cheap box and host it off their service.

It would be at another location, (should be) cheaper than hosting, and the data is somewhere you can get to it easier than data center. This is how I would probably do it.

This is how I do it. I have a $400 fanless, silent Linux box plugged into a friend's DSL line. Every night at 04:00 a script kicks off that uses rsync over ssh to sync both my Linux and Win2k servers.
