As you know, I have created an egg for CPS recently
(http://blogs.nuxeo.com/sections/blogs/fermigier/2005_12_16_cps-lays-big-egg)

The egg is big (12.3M) and exploding the egg at Zope on startup takes
quite a long time (1 minute IIRC).

But from a administration POW, I would prefer the implicit approach.

Regarding the startup time problem, I would vote for a timestamping
system (I don't even know if it's not the case already).
