This may really be a SMW bug... We have request queues for things like shell requests and project creation requests. It would be great to get Echo notifications when a new request is added to the queue. We'd have to have some way to determine who gets the notifications, too, though.
I'm not exactly sure how SMW can handle this. Queues are really just a search, so really this would be a notification subscription on new results in a defined semantic search.
This is outside of SMWs reponsibilities. One can hook into the prop update process and see if any new stuff is getting written, and then create such notifications. One extension goes in this direction, and might perhaps be used for the purpouse, though it is perhaps not as stable as one would like: http://www.mediawiki.org/wiki/Extension:Semantic_Watchlist
