both are possible. the default deployment would be to use a shared
provider jar. this also has the effect of moving all of hibernate's
runtime dependencies out of the wars into the shared area as well,
which lets us save PermGen space.

we could also share the api jar and any other jars depended on by
multiple wars. i'm not sure how much of a win that is, though; it puts
a dependency management burden on snarf, and it makes things more
difficult for people who want to use a container other than tomcat.

packaging an ear is a great alternative for people using ejb
containers, and we should eventually do that no matter what.
