It depends. If you use Flowscript or Javaflow then you'll run into a couple of 
problems and AFAIK the portal isn't distributable either. Fixing at least the 
Flowscript problem is on my mid-term todo list but don't hold your breath.

If you don't use any of the mentioned technologies it only depends on your 
application and what you put into the session. If you put a component into the 
session, that has access to the ServiceManager (form erthe ComponentManager), a 
NotSerializableException will be the result. Using the 'transient' keyword 
should help.
