I do this too. But tmpfs (why do you want to use ramfs?)

I call it /tmp-ram and I give it the same drwxrwxrwt permissions as /tmp.

I use it as the default place for all downloads.

Another example, I listen to streaming radio, and I rip it to disk (so I don't have to deal with buffering, and so I can skip songs). I put it in /tmp-ram, it rips from one end, and I play and then delete from the other.
