oss igoogle-like container projects?

[Matthew Russell]

Hey all -

Was wondering if anyone is aware of any OSS projects or anything out  
there along those lines for more sophisticated containers than the  
ones in the sample code? I'm thinking igoogle-like things such drag- 
and-drop, being able to maximize a gadget, and such. Surely there is  
some effort to create an oss container like that?

Would something like this be outside the scope of "Shindig  
proper" (and more appropriate for its own little google code project)  
or welcome as an addition to Shindig itself?
