I have read the styx papers. The concept is of course not new.
What I am talking about is packaging up as a reusable
component.  Specifically
- server side api
- ability to discover capabilities. no new client side drivers
  for each new device.

As for "simpler than 9p" I had a different thing in mind from
what is in various iwp9 papers. Not worth talking about in the
abstract.
