True enough about standards.  But MQSeries is a very good way to go if
you want guaranteed once-and-once-only message delivery, along with a
simple API, across a wide range of platforms and network protocols
(well, ok, two network protocols).  Of course, you do have to pay for
it.

Actually, I'm fairly sure that, when using IP as the transport, MQSeries
uses sockets under the covers.

Personally, I think MQSeries is an immensely strong technology that IBM
doesn't market nearly as hard as they should, probably because they
don't realise what they've got.

Now what does that remind me of...

Cheers,

Martin.
