Depends what you plan to use for the server.
My experience with Linux is limited to keeping a Suse6 server running for 3.5 years, using Webmin mostly and doing nothing even remotedly fancy
With WinNT and 2000 things look much better, but I must admit I havn't seen any 2003 server up to now ...
I would suggest to form a team from people all over the world anyhow, to have better chances that at least
someone is available at any time. Wouldn't be that good if the "official" server is down for several hours just because a single instance of Dom is blocking everything for some reason.
