Yes, this is exactly the job for a WFS protocol.  As Eric mentions, the 
work is mostly in the vector-behavior sandbox.  I'll make an effort to 
update that and to get a patch ready for the trunk.

My hope is to get the WFS protocol in the trunk before the end of next 
week.  Any help you can contribute would be appreciated.

Watch the WFS protocol ticket [1] for updates from me, and leave any 
comments/patches there that you put together.
