Luis Sevilla of gvSig is working to organize a bit of an 
interoperability to focus on better WFS performance.  Definitely high on 
the list of things to investigate is a nice binary transport format.

It would be very nice if the next iteration of WFSDataStore decoupled 
the WFS protocol stuff from the response type - I feel like they're 
pretty closely coupled now.  Ideally we could support the binary format 
we decide to use, and even be able to use shapefile as a transport 
protocol for flat responses, reusing our existing shapefile code.

Another option may be the bxml stuff that cubewerx was pushing awhile ago:
