I've heard a rumor that one of UI or USL have rejected JAXI as the
network interface of choice for X.25.  Can anyone confirm, deny
or elaborate on this?

I can't speak for UI, but I know they were looking at both AT&T's JAXI and at
Spider's XPI. I evaluated both, and found them both severely wanting. Both are
far too inflexible (X.25 may be mature, but it's hardly cast in stone; neither
could support X.25(88) without some structural changes). Both have inadaquate
error recovery. XPI is particularly bad at failing to isolate the application
from network quirks, like Reset and Clear collisions. If forced to one or the
other, though, I'd chose XPI; it at least anticipated new facilities.
