Just out of interest since cygwin was mentioned, has anyone tried out
the cygwin NFS server rather than the SFU one? If it were combined with
cygwin's "managed mount" mode it should in theory support ':' or other
similar names that are normally illegal on windows, although they
wouldnt be accessible from windows from what i remeber. Also I seem to
remember things were always rather slow when I used to use cygwin, so it
might not be worth it in terms of speed. Sorry if this is getting a
little offtopic.
