It is possible actually. Using dynamic mix-ins. e.g., mixing in a new base 
class to an existing class when the plug-in is loaded.

Using mix-ins, I don't think you would have to redesign it at all.

Sessions are more fundamental to application servers. PSPs, Cans, 
object-relational mappers, etc. are not.

I also assumed Cans would grow quite a bit. People have mentioned expanding 
the examples and providing better support for multi-threading. I'm sure 
other features will be added as well.
