As soon as I sent this I believe I found the answer.

I was sort of right about creating the new read-write (NOT readonly) 
snapshot.  After it is created simply delete the one which was created 
by btrfs-receive.

I also found out that if you want to rename a subvolume, siple do it 
with "mv" like you would for a directory or a file.

OK folks, do I have it correct?
