Subject Re: Interoperability with ExtJS

Dan,

Like I said in my reply to Joe, my head hurts of all the JS framework  
choices :-) I'd like us to design a service that can be integrated as  
a data layer into the most of the leading frameworks... (if this is  
even possible...) In this respect your experience with Spry and other  
things JS may be helpful to us. So feel free to jump on the  
discussion, that I hope will continue on dev.

Andrus
