Yeah, that is true.

Well, also true. Personally I always run firewall, so just remember
about it all the time.

Well, technically it should be of course slightly less efficient because
of PPP, IP and TCP header sizes, but with high MTU it should be not so
considerable overhead. The main issue is window scaling algorithm and
TCP on null-modem and similar links is good enough. Also PPP exists in
OS (*BSD) out of box, comparing to UUCP or ZModem-utilities. And also it
allows online protocol usage immediately. I am not trying to persuade
PPP usage, just personally my struggles stopped me at that solution :-)
