Ah, ok, this makes sense to me.

I would probably make the net.ppp namespace pretty transient and that
way you wouldn't need the net.ppp.link property.  Either a device has
the net.ppp capability (and thus has a link, etc.) or it doesn't.

Yep, these seem good.  I hope they're available outside pppd; it'd be
great if they were in sysfs.
