I'm not sure what the "framing type" in an L2TP session signifies - does
it signify what framing is used for the PPP traffic once it leaves the
L2TP tunnel, or does it (for some not-entirely obvious reason) signify
what framing is used *inside* the tunnel?

I don't know any more than you here.

RFC 2661 says
[...]
which sounds as if you're *not* supposed to send PPP frames over the
wire in RFC 1662 byte-stuffed form.

I'm inclined to agree with you here and the comments about CDMA2000.

But all of the real CDMA/1xRTT stuff is ITU defined (= $$ to obtain.)

What about

Thanks, I'll have a look.
