Scott,

Yes you can, and I did so previously. However whatever you install, it may 
be a tiddlywiki server, or AMMPS LAMP MAMP or some other server they 
typically use port 80 or 8080 on 127.0.0.1 out of the box so a chance of a 
clash is high. You thus have to manage it.

Bob will grab the next port but the local links will need to change if the 
port changes

I moved to additional IP addresses for on my lan so I could establish a DNS 
entry for Bob as an example on its own IP address. If later I move Bob to 
another computer I just move the additional IP Address as well and it will 
continue be at the same address.

However this breaks down on a new network, without the same DNS or network

This solves the new network and local host problem by moving the server to 
127.X.4.X fixed address, so it works no matter the network on my laptop and 
will only be available on the LAN if I am on the "correct" network

I have not done it yet but I believe I can set it to be available on the 
LAN using one of my "Additional" IP Addresses however multiple servers will 
always be locally available with the custom 127 address's and will use 
whatever port they want with no need to increment up to an available port.

Is that a little clearer?

Regards
Tony
