Seeing the amount of reactions, maybe it would still be an idea to form 
an interest group for this? One of the things I'd hate to see happen 
(and what is happening already) is all these initiatives being explored 
parallel, whereas IMHO we should be combining forces on this as a 
community, since it is a significant effort which also needs careful 
thought.

Could space be arranged on the plone site for instance for an interest 
group to communicate? What do others think?

Best regards,
Bart
