I'll have to play with this. The problem is that on a failure, you never know 
when the server is going to go down. Makes me wonder if I could have a simple 
script going which constantly sends the updates to a shared drive and some 
heartbeat mechanism on standby machine/s so that if main server goes down, 
another quickly takes over.

Wonder if that's the idea behind the link that Rob sent me. No need to 
re-invent the horse, looks like there are in fact lots of ideas out there.
