- zope restarts faster

- you can connect to zeo with another zeo client and do administrative
or debugging tasks without slowing down or interrupting your main zope 
server - e.g. packing, debugging with python.

- raw zodb performance is slower

- you must take care to protect the zeo port. A sufficiently 
knowledgeable person with access to the zeo port can get
access to anything in zope regardless of security settings.

sure, but to make good use of smp you need to keep each python process
bound to a particular processor. How to do that depends on the
OS.
