ZEO 2.0 and Zope 2.6 are independent releases.  You can use Zope 2.6
with ZEO 1.0, and you can use ZEO 2.0 with Zope 2.5.  

The CVS trunk currently has ZEO 2.0.  This change was made a couple
weeks ago, independently of the Zope 2.6 release cycle.  It may be
that you interpreted that change on the ZEO trunk as an indicator that
you must use it.

I am able to run ZEO 1.0 on Zope 2.6.  Does the ZEO test suite pass
for you?  That's spelled:

    python utilities/testrunner.py -d lib/python/ZEO

assuming that you installed ZEO in the lib/python directory.  If they
don't pass, can you send me the failures.  Most of the ZEO tests run
correctly, but I see a few failures caused by a change to the test
framework in Zope 2.6.  Here's an example:

ERROR: checkUndoCommitVersion (testZEO.ZEOFileStorageTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/home/jeremy/src/Zope/lib/python/ZODB/tests/TransactionalUndoVersionStorage.py", line 113, in checkUndoCommitVersion
    revid = self._dostore(oid, revid, description='packable%d' % i)
TypeError: _dostore() got an unexpected keyword argument 'description'

I'll fix these problems for a ZEO 1.0.1, but they don't indicate a
serious problem.

If you check the ZEO 1.0 tarball, you'll find a trigger module in it.
Perhaps something was corrupted in your installation.

I don't quite follow.  Can you explain exactly what went wrong when
you tried to run the server and client from the same directory?  I
assume this is a problem with ZEO 2.0.  What do you mean by "the new
startup stuff"?
