Yes, I've thought about it.  The trick is to decouple the actual 
MTU/segment size from the size of the segment we actually build in 
tcp_output(), then setting a flag in the mbuf saying "hey, segment 
this".

I don't think it'll actually be that hard to implement, I just haven't 
gotten around to it yet.
