people have suggested sending the subscriptions upstream, with an 
identity and building yr own filter which knows where to send the data.

there's a pub-sub thread on this list about these things.

I am experimenting with trying to get the inter-thread case working in 
my spare time, after getting some pointers from Martin S.
Martin S posted a what-needs-doing list for tcp etc earlier on. It's 
quite involved.
