Yes, I do see that.  I'm running ZEO on the ethernet address not the
loopback address (that's specified in custom_zodb.py for the ClientStorage
and it's specified in zeo_start, the shell script that invokes
ZEO/start.py).

Here's what I get:

  $ telnet 192.168.0.2 8800
  Trying 192.168.0.2...
  Connected to 192.168.0.2.
  Escape character is '^]'.
  Z200^]
  telnet> quit
  Connection closed.

The ^] after the Z200 is me hitting the escape sequence.  ;-)

Holy cow, this puppy is big.  I stopped Zope, stopped ZEO, deleted the logs,
restarted ZEO, restarted Zope.  At this point, before even making an http
request, the ZEO log is 700K.  I won't send this to the list.  I can send
the whole shebang to you if you like.  The tail below may be sufficient.

OK, I just made the first request for http://localhost:8080/ with Konqueror.
I get the home page, but it seems to be stalled on the powered by logo.
Hmm, it stopped eventually, without rendering the logo.  Now, subsequent
requests timeout.

Here's the very tail end of the ZEO log with my comments encased by **MM:

** MM: At this point, Zope was started.  I waited a bit.  And then I
       navigated to http://localhost:8080/).  The following entry is
       all that's left in the ZEO log:
