Just for the curious, Apple's MacAPPC product does provide (1) as
well as (2), although I believe the actual implementation for talking
between two LUs at the same node is a little strange.  To the TP programmer,
however, it is very straightforward to do both these things.  This doesn't
help you for AIX, but you could always buy a Macintosh :-).
