Yes, now that it's been pointed out (by not only you but someone else,
I forget offhand who), I realize that most (all?) of my problems with
PPP for this application are actually with pppd.

That's an attractive option; I didn't know it could be done.  How would
I go about it?

It's not clear whether you're proposing I use some (hidden?) option to
pppd that bypasses most of its code, or write an slattach-alike that is
like a rudimentary pppd and doesn't do all the LCP/IP{,6}CP stuff
(which I think is done in userland - right?), or create a new
pseudo-interface that has an interface like sl but uses PPP's
encapsulation, or what.

Perhaps I'm just exposing my ignorance of the PPP implementation here?
