For #1 you're talking solely about nested SFSBs sharing the same XPC, right? I did suggest some things for nested SFSBs, specifically, having the parent SFSB manage the bean instance, injecting the bean instance into the child proxy and passing the instance along in the invocation payload, thus bypassing the child's cache.
