For this to work, I'd need to be able to delegate all other sockets back to the standard implementation.  Unfortunately, it appears that most of the classes I'd need to access are package-private so this approach wouldn't work.

I can't point to specific examples but SocketImplFactory is somewhat 
legacy now. It was used quite a bit in the early days but personally I 
haven't seen any usages in the last few yeas.
