Any recent project I'm involved in seems to require a more real-time-ish experience, and PuSH/PSHB is a very elegant and pragmatic solution. A very nice add-on is that it supports simple private update streams (you can for example push profile updates to selected people in your address book w/o too much hassle). What I also like is the ability to hook into the wealth of RSS/Atom feeds already out there, even though you still have to implement a polling mechanism for legacy feeds that don't support pub/sub yet. PuSH needs asynchronous processing and job queues, and writing a compliant hub is not trivial. But compared to implementing RDF specs, I dare say it's pure joy ;) For resource updates and predicate-level changes (maybe even object- level, not sure yet), I'm looking at Atom Activities[1]. They are a bit like RDF, and more obvious than a directly embedded SPARQL/Update query. Translating incoming RDF activities to Talis Changesets or SPARQL INSERTs/DELETEs seems to be straight-forward, but I'm not there yet code-wise, so this is really just a guess so far.
