Neat :)  Thanks for protocol documentation, too.  Do you plan to add 
write-pages in addition to write-page?  Also, write-page does not appear 
to be documented.

Is race-across-directories race-free?  That is a sticky area, see 
Documentation/filesystems/directory-locking in particular.

With the exception of encryption, do you think the POHMELFS client is 
mostly complete, at this point?
