With 2.2 blocks are only deployment units. Within Cocoon 2.2 there is no concept 
of blocks, no blocks protocol, no shielded classloader (I know that you know but 
just to speak it out)

hmm, not sure if I understand what you mean. IIUC each sitemap has its own 
Spring bean factory (container). Do you want to make the classloader, which is 
used to create the bean factory, configureable?
