One very major problem with that idea. Computers / servers etc do not
'Run from HD' or 'Run from CD' - everything runs in memory and is as
vulnerable to attack as any other PC that's not locked down. Servers
by their very nature are designed to be open to all so locking them
down against attack is not as simple as running an AV program or
Firewall.

Also running a server on a home DSL service has its own issues,
firstly the data traffic that it's likely to generate and secondly
your ISP more than likely expressly forbids it in their T&C ( due to
this high traffic load ) so you'd run the risk have having your
account pulled if you persisted - you'd get a warning or two first I'd
expect.

The suggestion of hosting on a reliable service and keeping local
backups is the way you'd need to go IMHO.
