From the "perhaps this might be interesting" file...
Since the end of the HealthVault Solution Providers confererence in early June - and the subsequent required recharging - I've been spending the bulk of my time working on HealthVault data types, along with one of the PMs on the partner team. It interesting work - there's a little bit of schema design (all our data types are stored in XML on the server), a little bit of data architecture (is this one data type, or four?), a fair amount of domain-specific learning (how many ways are there to measure body fat percentage?), a bit of working directly with partners (exactly what is this type for?), a lot of word-smithing (should this element be "category", "type", or "area"?), and other things thrown in now and then (utility writing, class design, etc.). 
Definitely in the "interesting file." Please post more details :) I would love to hear more about this.
