As far I know, these RFCs were early draft and were never completed nor submitted. I think the 9P2000.u authors moved to a new approach, which was called 9P2010 and is now called 9P2000.l. I don't know anything about it however. Anyway, plan9port applications only speak 9P2000. -- David du Colombier
