Were you encountering the same errors with other versions of emacs or
just with the unicode-2 branch of emacs 23? I suspect that most distel
hackers are using either the latest Emacs (22.1, released on June 2,
2007) or "standard" CVS emacs or some pre-22 release of emacs. 

If the problem only occurs with the unicode-2 branch of CVS emacs,
have you investigated the possibility that the node communication
might be undergoing a unicode transformation and thus not being
interpreted correctly in distel? You should be able to verify this
if you:

1. Start up emacs 23-unicode-2.
2. Do (setq fsm-use-debug-buffer t) so that you can trace the node
communication.
3. Do the sequence of distel operations that were failing for you
before (presumably, this was just connecting to the node "C-c C-d n"
and trying to run some command like list processes "C-c C-d l").
4. Save the contents of the *fsm-debug* buffer (you might want to also
switch to hexl mode and save the contents in that format too).

Then, do the same sequence of operations in emacs 22 and compare the
contents of the *fsm-debug* buffer in both. Hopefully, that should
provide some clues. If it's not obvious what the problem is by
comparing the debug logs, you'll have to see what messages the node is
sending. Luke provided some links in an earlier email to documents
that describe the node<->node protocol:
