Current status of CFS for linux?

If you do not know what is CFS, do not bother... For years, I have been and still am a happy user of CFS. I have not paid any attention to its development. I am now concerned though whether it has become obsolete. I am creating nightly backups and backup the encrypted CFS tree. What I am concerned is, if my computer crashes, perhaps I will have difficulty restoring CFS data on other computers. I noticed that there is something called TCFS, which is derived from CFS. Is it binary compatible? That is, let's say my home computer dies and I have the backup CDRW. Can I take the encrypted tree to some computer running _TCFS_ and decode the tree? igor
