I would guess that this is not so much dependent on ACE as it is on your
definition of "real-time" and which network stack you use.
Some would say that you would need something like RTDM within Xenomai or
RTAI to ensure network real-time performance, but perhaps your needs are
not quite that stringent.
You might achieve "good enough" by using local timing services and local
NTP to get within a few microseconds, but of course that would not
guarantee execution ordering between distributed processes.
