Hi Steve,

This solution would be perfect, by my problem is that Im renting the servers
in the datacentre and I have no physical access. The servers are with
fasthosts.co.uk so I cannot do something like this. I can only communicate
between the servers using TCP/IP.
Thanks for your recommendation though, I would love to be able to use it.
