Halfway. Client (connect()) sockets are possible, servers (listen())  
are not. (I've written the code to support listening, but it doesn't  
work and I haven't gotten around to finding out why, so it hasn't  
been committed yet.)

However, an old project of mine was EIO implemented on E-on-Java. I  
lost interest, but the code mostly works, though the interface for  
creating socket streams no longer matches how I think it should be done.

I have now published the source in its current state:
