I think you have to look in the source code if you want to
develop your own filesystem type. (I'll be happy if I'm
wrong about that.)

Release 3.0

I don't think vendors HAVE to include it under SVR3 licensing
provisions, but it would be pretty foolish to deliberately
remove it.

Pretty much.

I think it would be possible to support this, but I don't
know whether vendors will.

That's actually a good idea. Note that Apple did this in their
GS/OS, which has the moral equivalent of FSS.
