We currently have two user file system frameworks in ports (fuse, Arla nnpfs) 
and one in the kernel already (Coda).  And no doubt more I don't know about. 
We're actively discussing importing nnpfs to make access to AFS easier out of 
the box.  I'd be careful to recommend a determination of whether it makes a 
useful further contribution or not, rather than just recommending a port of 
the code.  I have a loose recollection from the AsiaBSDCon puffs talk last 
year that fast path access to local cache (container) files wasn't implemented 
in puffs, which would put it at a significant disadvantage performance-wise to 
nnpfs.  However, a year is a long time, so it may well be that puffs has now 
picked up that support in the mean time.
