We have no plans for a WHS aware version of Tardis. Yours is the first request we have had in fact.
If we get a lot of requests we might reconsider but for now it isn't on our road map. Vista support is on the road map but only after the dust has settled on the release
i.e. after it has been fixed.

It sort of works already as a service, but adding in the interface would make it much more usable since WHS servers are supposed to be headless…
Finally a possible solution for a home network time server… (using an Microsoft GPS) 
If so, id be more than interested in a beta version
