Has anybody installed the new Palladiom Tstat now available for HWQS?

I have a project where I've spec'd the Honeywell TouchPro for the client, though we are using Palladiom keypads everywhere and at the time the Tstats were not available for HWQS. Now that the Palladiom Tstat is available I'd like to put together a proposal for the client to upgrade to the Palladiom Tstat.

Reading technote 3691033.pdf it indicates that the Heatmiser interface is required for in-floor heat systems, after reading further it would appear quite a bit more hardware will be required to integrate the Palladiom Tstat into the system.

Anybody have direct experience yet with these new tstats ?
