I assume you have private/secure links between the offices?

This can be solved by rsync (or similar)

you can switch realservers in and out by running ipvsadm commands.
Currently mon (from the Linux-HA people) is used to detect realserver
failure.

No-one has done this, but it should be do-able with a bit of thinking.

The real problem however seems to be the NT machine crashing. If you 
substituted an apache/linux machine with a MTBF of years, would you 
still have a problem? (I expect your tcp/ip connection between offices
would be out at least once a month).
