Does the posix mqueue's not fit your need ? Have you tried them ? Do
have some kind of numbers about your definition of fast ?

For me, the POSIX mqueues seemed to work, though with some initial
trouble which was fixed with a patch to the kernel follow this thread
( http://lkml.org/lkml/2010/4/2/293 ) , this patch is now queued for
mainline inclusion for 2.6.35.

There is also a new test suite to measure message queue perf in the
rt-tests. Its called pmqtest.

regards
