[sldev] Re: Inventory Loss due to capped IM's

A couple of us have been investigating RabbitMQ (Erlang implementation of
AMQP) for a couple of applications, and this seems like a potential
application for it, along with moving offline IMs completely out of the
database. You send a transactional, persistent message with the inventory
offer, which would fail if the queue was full or it otherwise couldn't be
placed in the recipient's queue. It would then sit there until the reipient
accepted or declined it or some interval had passed, after which it would be
returned to the sender's lost and found named something along the lines of
"declined/expired inventory offer to X: <original name>".

Just a thought. I haven't actually discussed this with anyone :) Note that
we don't have RabbitMQ in production anywhere yet, and we don't even know if
RabbitMQ or AMQP will work for any of our purposes.
