Thanks Lester,

This gives me more scope, and price wise £26 is not a huge outlay.

Lester, looking at your site and Tibo's there seems a lot to choose from.

Any idea of price and availability of http://www.crownhill.co.uk/tibbo/EM202.php - EM202 unit and is this a suitable unit for converting the TX / RX TTL lines from a PIC to Ethernet ?

The EM202 is an older part, the above links show suitable replacements.

Doing a bit of homework and it seems most apart from one of these devices are designed for 3.3v operation and don't run in an 5v environment. I was also bragging that the 4ch thermostat project that I've been working on maintains a st temperature to within 0.5 of a degree (+/- 0.25C) which I can live with (Thanks DT and Henrik), when my boss asked if it's possible to network the device and with modification, come up with something that could monitor temperatures in the server room. Would the following work (is it simple too)
