DataSkins and Zope3 was Re: [Zope3-dev] Groups and Roles *not* interchangeable

[Steve Spicklemire]

Hi Phillip!

I'm glad to hear your voice in this duscussion! I'm very interested in 
seeing LoginManager, or at least LoginManager features avaiable in Z3, 
if not "built in" at least "possible". In an earlier thread you 
mentioned that the new Z3 component architecture would remove the need 
for ZPatterns altogether. I've snooped around the Tutorial, and the 
Wiki, but I'm having trouble seeing how you'd be able to do something 
like DataSkins in Z3 without ZPatterns. Would you mind elaborating just 
a bit on your line of thinking here? Is this where TransWarp could allow 
you to "weave" whatever storage option you like? Will it be as flexible 
as SkinScript attribute providers and agents?

thanks!
