The idea is to have a permissions-based community-shared, singly or shared ownership of an iGoogle Page for all to view - when permissions are granted. Also, for instance, my iGoogle Personal page could be viewable, changeable, addable - to another's iGoogle page or website or blog.
Goole Apps already has the implementation where an iGoole page is public, this would just allow other to modify elements, color, overall design (using perhaps either GreaseMonkey or Google's own design system for blogspot pages).
The concept being anyone could be given permission to "have some fun" re-doing a page. Not quite Wave, but something along those lines.
Of course all this genius stuf could only be made viewable using the appropriate plugins while using FireFox to view and edit. I'm thinking Ajax or Ajax-like.
In addition, a sharing of CLEO - I want my CLEO collection to be available for download - this is different in that to date only programmers and creators of plugins are allowed to post CLEO clumps, I want my 90 faves to be made available in a a nice bundle like CLEO-ized (Hey everybody, try ALL these that I use quite a lot of! Download here!)
