X.25 has been implemented on various machines under Unix, Xenix, etc.
Some companies offering such that come to mind are TITN, Systech,
MorningStar, Gateway/Source, The Software Group, and XDot.  I'm sure
there are others, but these are the ones I've found have more than
vaporware.  

** Begin Product Non-Announcement **
I don't know if anyone has X.224/X.225 available commercially.  We 
will be building it into our Electronic Image Transmission products; 
currently we use T.70/T.62 which are also CCITT protocols (and are 
subsets of the full X.224/5) geared towards document/teletext/facsimile 
usage.  We run X.410 and X.411 P1 on top of all that.  I don't think
there are any plans to sell just the comm software, but the whole
product complete...
** End Product Non-Announcement **

I know that AT&T Bell Labs folks are interested in this and there has
been much discussion in the net.mail* newsgroups about uucp, RFC, X.400
and ARPA domains and how in the hell they all fit together.  Comments?

??? Anyone with any such products want to say?

I would like to start a group for that, but isn't net.dcom the right
place for that?  (And of course net.news.group for the proposal.)

The German PTT (Deutches Bundespost) has an X.400 system operating
today, tho I don't know any more than that.  KDD (Japan) has
interconnected with Univ of British Columbia in their X.400 mail system.
