  +This is preliminary design document on the organization of the host
  +component of the USRP inband signaling implementation over USB.
  +Assumptions: we'll have a single usrp_usb_daemon, implemented as an
  +mblock, that will provide the high-level message based interface to
  +the USRP.  The daemon will handle all resource allocation, muxing and
  +demuxing for the control and status messages from multiple clients.

It would be nice if the design for in-band signaling treated USB as
the (current) special case, and was done with GigE etc. in mind.  I
didn't see anything that jumped out from this viewpoint, but earlier
is better to avoid trouble.

Do you expect that allocation of capacity is anything more than
internal control within the usrp daemon?  That conjures up isochronous
bus transactions and OS-level reservations, but I don't think you mean
