Occasionally you see a solution that is so cool you have to buy one just to play with it! This card is a little webserver (and it can send emails!) with ethernet, 16 x digital i/o (GPI ins and relay closure for o/p in tele talk!) and 4 analogue i/o channels. It also has an RS232 port. All of these are accessible across a LAN or the internet (if you configure a static route through your router). Most significantly is that two of them will talk to each other and so extending button pushes, lights, buzzers, temperature probes, alarms etc. between buildings is possible. The best bit (for me!) is that you can extend a serial connetion across the internet and according to the manual you can tweak latency so that for time-critical applications (controlling a VTR via the P2 protocol) you could optimise it.I shall report when I've got it in and tested it.

i bought a netiom card but lost my programming link (the small black part that covers the programming pins) is there anything i can do to be able to program it again?
I'm guessing you're new to electronics! My toolbox has several dozen kicking around in the bottom.
Anyhow - they're called 'jumpers' or 'handbags' and all the electronics stores have them;
