I don't care about the likes of "ls \\foo\bar"; that was just a quick 
(or, rather, a slow ;-) way to demonstrate what could happen.  My real 
concern is for programs that issue equivalent system calls: if you add to 
them some loop which walks all the possible devices trying to find the 
mapping, you will slow down the system calls to a crawl.

Not even a floppy is that slow, and with floppy, at least you hear it 
grinding, which gives you some clue about what's going on...
