I would totally love to have something like this. Servers aren't terribly expensive to rent out, but we could always run a donation for whoever decides to run it.
I'd like to run it at home. I've got a stable environment, good bandwidth, US located. I'm going to wait until I get the new networking hardware I ordered installed before making it live though. The only block preventing this from working well is my current router (2003 era, 200mhz and always has 100% cpu usage). It's dying and I've got an ASUS Dark Knight in the mail (sick router). After some minor changes to the WAN, DMZ and Firewall it'll be up and running all stable and the like no worries at all

Past that if anyone is interested in running a donation that is fine by me, but I'm happy to run it for free.
