It is never going to work if you don't plan for it. Customers will ask for this, and in fact 
many will expect this to work, so prepare a workaround for 4<->5 and put it in your roadmaps 
for 5<->6 :-)

I mean it might be hard to do it between 4 and 5, but between 5 & 6 where the codebase is 
uniform it should be easy to make it work without isolated classloading.
