[Zope] finding an object at startup

[Albert Ting]

Is there a way to fetch a particular zope object from within the
__init__.py product file?  What I'd like to do is modify my ZSQL database
connection adapter from within a python hotfix, rather than startup zope
and set it via web/manage interface.

In fact, if my SQL machine is forced to move to a new location, I may not
even be able to startup zope.  I've also tried hand editing the Data.fs
file, which didn't work.

Thanks,
Albert
