Since I like talking to myself so much, I thought I'd reply with some
other backing thoughts.
We currently implement this within our own repository class. When it
sees a request for ISomething, it consults a map and converts that to
a request for Something. I've been looking at using ActiveRecord
again (we moved away from it due to this interface mapping issue) and
I've considered implementing the interface mapping in ActiveRecord.
When I thought about it further though, it seemed more like something
that ActiveRecord shouldn't need to worry about (aside from the
mapping perspective) and something that should be implemented in
NHibernate itself. Obviously it would be nice if things like Linq and
QueryOver worked against the interfaces as well.
So, to summarize, I'm pretty sure that the ORM is the one that should
take responsibility, and that's why I'm interested in implementing
support for this in NHibernate.
