Yep, as Arunoda says I'm actively working on it right now, currently hoping for an initial release this month.

I really appreciate the work Arunoda has done on smart collections; my implementation and his package have both learned from each other. That said, there are a number of subtle race conditions involved in synchronizing queries between the oplog and the main database, and working out all the little details as carefully as possible has taken time!
