[Zope3-dev] zope.app.twisted.main and zope multiservice

[David Pratt]

I am wondering if as part of bootstrapping zope, that a utility could 
not be set up in the site manager that could hang on the zope 
multiservice object. Methods available for the utility could allow you 
access to this after booting zope. Is this reasonable? Many thanks.

Regards,
David
