User-ppp has a few things that (AFAIK) pppd doesn't have. Multi-link
is the big one, there's also terminal mode, aliasing (w/ transparent ftp,
nbt, irc & cuseeme support), packet filtering, ppp/tcp,
ppp/some-arbitrary-program, diagnostic port connections, dynamic IP
assignment and DNS negotiation (*client* & server).
I've also got some initial mods for radius support, but they need
some work (only authentication is there at the moment).
Of course pppd has its advantages - less passing of packets in & out
of the kernel for a start - and BSD compression. I'm sure it's got
others too....
