Securing funding for these things proved to be quite difficult. I've 
recently started looking into this again (and a big cleanup), but it's 
vaporware at this point.

That said, GWC has something called request filters, which were written 
to support datasets with sparse coverage. The included implementations 
use 1 bit rasters generated directly by the WMS, or pregenerated files 
from disk. It's not well documented, but you can find it in the 
configuration schema docs. A request filter based on shapefiles was also 
submitted to the list two days ago.

If a BoF session happens I'd be very interested in a summary, 
unfortunately I'm not able to attend this year.
