That much we can guarantee :-)

I think ExtJS also goes with a single commit of multiple changes -  
something that we certainly want.

I think it is. A few things to note:

* Let's move further discussion to dev@cayenne.apache.org, as backend  
design threads tend to be long and boring for most end users, even if  
they are interested in the final product.
* My brain hurts because of the number of choices in the JS world, and  
we'd like to keep our design as portable as possible... But we have to  
start somewhere, and from what I've seen so far, DWR remoting seems  
like a good starting point, so let's maybe concentrate on that for now.
