Since we have the ddk now, what about making Cygserver into a System 
Device Driver (sys) in the same fashion as the driver for ioperm() or 
WinPcap?  Of course, this could easily open up another can of worms, but 
doesn't U/Win & SFU already do this?  One could also considier the 
potential performance gains by going this route.  It would be easier in 
that users wouldn't have to remeber to turn on server, but I suppose 
problematic in that we'd have to worry about a file installed outside of 
the traditional Cygwin tree.

Cheers,
Nicholas
