Do you want to?

When:

   mvn -f maven/pom.xml install

is executed, have a look in the jersey/dist directory, you should see:

   jersey-0.8-ea.zip # binary distribution
   jersey-snapshot-0.8-ea.zip # workspace/source distribution

those are pushed to java.net by Hudson.

Yes, and the binary zip too.

The requirement is: don't break the existing ant behavior while we are
transitioning.

OK. I think i am being too paranoid in this respect!

I was more thinking of using the Jersey Grizzly container directly, then
it would be up to us to write it. But a general plugin for the Grizzly
servlet container would work and i think would have wider appeal.
