Hi Jeff,
nice to see that you're still around..

The first methode is pretty much what I had in my mind as I thought it  
could be done really fast provided that we get hardware support for  
blitting with a transparent color up. Since it however doesn't seem as if  
the xfree86 drivers support this technique I agree with you that the  
second approach should be better.

I sure didn't write an 18 pages paper about nano-kernel design to put such  
things in the kernel ;)

- Each mouse/keyboard/graphicard has a driver of its own that multiplexes  
the device
- All HIDs give the terminal server full access to their resources
- The terminal server creates a binding between the devices

To support multiple clients per machine all that would have to altered is  
the terminal server, which is probably the part that comes closest to x11  
in my design.

It's definitly not a top priority but nevertheless eyecandy is still the  
best way to get some attention from the community and attract new  
developers..
