I don't like the fact that data queues won't produce an error if there's
no program listening for data on them.  I want to know that the program on
the other end is listening and responding in real-time.

I'm not usually interested in storing data or queueing it up to be
processed later.  I'm interested in real-time program to program
communications.

I also prefer sockets for portability. Sure, IBM has APIs for sending data
queues on Windows, but you have to install their software and pay them for
it's use. When I want to go to another platform such as Unix, data queues
aren't available at all. They're not an industry standard, they're an IBM
proprietary thing. Sockets, however, are available everywhere and are
integrated into every operating system.

I have scales (for weighing products) that I can write programs on and
that have a sockets interface. They certainly don't have a data queue!

This is not an absolute thing, however.  I do use data queues, and there
are places where they're more appropriate.  However, for me it's been
rare that I use them.
