It occurred to me that this might be something that an Arduino (or any 
other PIC board really) could do, so I googled 'arduino clid' and got 
quite a lot of hits.

However, there didn't seem to be any pre-rolled answers.

One person somewhere suggested using Asterisk or FreeSwitch and 
certainly that would be one good quick (if elaborate) way of getting 
CLID. Of course one still needs some interface hardware and the usual 
POTS boards for both are quite expensive (having bought them!); however 
apparently X100 clone cards are available quite cheaply...
