yes it is rcs-revision but "cvs:rcs-revision" sounds ugly. Perhaps it is
as good as "cvs:file-revision" (which would be the exact term compared
to "git:revision" on the root directory)

(This way my sync namespaces still exist. E.g. synching with two
different cvs servers is still possible "cvs:revision" vs "cvs2:revision")

I didn't believe it possible (given that execute and binary attributes
do not make sense on directories).

good point! (having parts not tracked by cvs I never imagined)

Ugh. I don't want to go that way (e.g. connect to different servers to
update a tree)

(I did not yet grasp the meaning of svn branches and expected it to work
similar to cvs branches)

Synching between different systems was a goal of cvssync from the beginning.

Working perfectly is a high standard given things like propagates,
directory renames and such. ;-)
