	It buys you generality, that is what it buys you.  Think man!
It makes everything so @#$!@$ easy if you use a IOStdReq (or similar)
structure.  Look at all the problems people have had with devices because
the designers didn't stick to generic base structures (an IORequest is
the base structure, but inadequate.  The IOStdReq should have been made
the base structure).  And now you want to do what?!!

	An IOStdReq has all the necessary message junk,  you can use other 
fields (like io_Offset) for other purposes, and it's big enough that most
commands will be in a STANDARD EASY TO USE format.  It is, in fact, a very
compact and useful structure.  I don't want to have to use ten thousand 
different custom structures when I use this system!  I want to be able to
(write/use) a RUN TIME LIBRARY to handle MOST FUNCTIONS SO I DON'T END UP
WRITING 5000 LINES OF CODE TO SUPPORT THE G*D*MN SYSTEM!

	For instance, sending and receiving messages, creating message
ports, basic functions, masking of unwanted or unsupported messages, 
searching for named ports, disconnecting, etc... should all be placed in
a RUN-TIME library and NOBODY should make assumptions as to what it 
does.... just that you now have a port that you can receive messages on
(etc...).
