Bruno and me talked about that layer a little bit at LSM2004; I'm 
attaching the result.  This is a possible interface for "device object 
that can be plugged in a buffering layer" that can be implemented by a 
user.  We also had this neat idea that these device-streams can 
implement the Gray byte-oriented protocol as well, for users that want 
to operate on unbuffered streams.

First draft, perhaps oriented toward files a bit, etc.  (I know Dan is 
thinking about a buffering layer; perhaps this lower part is useful for 
inspiration or something.)

Cheers,

Rudi
