This is something I have been working on for a while.

My thermostat was switched live 230V (like a light switch)
I purchased a relay kit from Quasar (part 3084) which allows me to switch
the 230V using a 12VDC input. My original ideas was to use an X10 DC
adapter
(http://www.letsautomate.com/10681.cfm?CFID=8471&CFTOKEN=4325835)
but that
didn't work.
Not being clued up on electronics I can only assume it is because that unit
is 100MA (does that sound feasible, anyone?)
Instead I am using a 500MA wall wart in a TM12U. The good thing about this
is the TM12U doesn't have current sensing, and it can be polled.

This setup isn't very pretty, which sounds like it might be a problem for
you. I'm not bothered as it's all in the garage.

I also use a Quasar temp board and eventually want to set the heating using
these (and HomeSeer). At the moment I still use the boilers built in timer
and just using the pronto to turn on the heating if it needs a bit of a
boost.
