Well,
Here's what I'm doing now.
I'm looking into getting a hosting company to donate a vps/vds system. This is the same type of system on which CD runs. Here are some descreptions of a vds/vps system:
The Virtual Dedicated Server is a full-fledged (FreeBSD stable) unix system. The VDS administrator is effectively the root of his/her unix system, being enabled to perform the whole range of system configuration and administration tasks, save the hardware management. The VDS closest relative is the standard dedicated server placed at a technical hosting site (a data center) and provided with a dedicated Internet connection.
Virtual Private Servers (VPS) provide the control, reliability and security of a dedicated server at a minimal cost. Ensims Patent-pending Private Server Technology is used to 'slice' a high-powered dedicated server into private servers. Each VPS has guaranteed system resources (CPU, memory, disk space) and its own dedicated system files. As a result, your VPS is not affected by another VPS that resides on the same physical server even if that VPS crashes.

We could use some type of ftp to sync with other servers if they wanted data, or mysql accounts, not to mention xml files.
I'll keep you all informed on a reply.
