What about dependencies like spring and hibernate?  We would have to 
package those in each webapp, which would cause snarf to double in 
size.  We could put them in tomcat/common/lib, but that becomes a 
problem when people want to deploy cosmo to an existing appserver and 
use conflicting versions of these libraries.  Or we could package cosmo 
as an .ear, but that means switching app servers.

This is something we should probably do regardless, because people are 
going to want to use some type of SSO to authenticate in cosmo.
