They are only similar to the extent that they are both essentially
proxy agents.
ppp -alias (and natd) strive to allow transparent access through a
gateway from an un-registered LAN using only one real IP number.
"Transparent" is the key bit.
Socks supplies proxy services where the machines on your LAN ask
the socks daemon to do stuff on their behalf and send back the
results.
ppp -alias and natd give you very little control. It's not their
job (look into ipfw if you need to control connections).
