I'm unforgivably implementation-oriented, but: whaa?

a queue requires an RPC to enqueue and an RPC to dequeue, so it's not as if 
there is any difference in scalability, security or local/remote-ness. 
ie enqueing is a sort of fire-and-forget RPC that doesn't do any work.

I guess the main difference is really architectural: with queues as the 
building block, you need an out-of-band, "meta" coordinator to track 
success/completion, whereas the RPC approach can handle status in-band.
