I pushed out cwfs(4) to sources last night. This is a port of Ken's
file server kernel (/sys/src/fs) to user-mode. It doesn't require IL
and hasn't been tested with IL, but it tries to be agnostic about
transport protocols, so IL might work. IPv6 should work but hasn't
been tried. It has been used to read emelie's main file system on an
HP 1200EX optical jukebox, and even produced an automatic dump to it,
unintentionally. It has checked, read and written emelie's other and
temp file systems too.
