I don't think server hardware is a pressing issue at this time. There are no
enterprises using Trisquel and the projects which might can be run from VPS.
Focusing that energy a little and getting a VPS company like Gandi or Linode
to offer true Trisquel images would be better. At the moment you can only
Trisqualize an Ubuntu image.
The best thing I think somebody could do right now is co-locate two servers
at different data centers which are redundant and use high quality hardware.
Then lease VPS's to others.
I think there are three projects/organizations/companies using Trisquel on
the server. ThinkPenguin will be one of these when our new site is up, the
Trisquel project is running Trisquel, and finally the Free Software
Foundation is running Trisquel.
If there is anybody else running I'd imagine its even less critical the the
three of these.
