Can someone comment on what CIPE still has as an advantage over OpenVPN
(does it have blowfish?) and whether these could be merged in the
future?  Cipe has served me well and I'd like to thank Olaf and everyone
else involved in its development.  For most of the time I've used
it there was no other free software that would have worked. I don't
have an immediate concern for security in the places I'm using it,
although it might make sense now to drop an ipchains/iptables filter
on the cipcbn interfaces to catch the possibility of udp/icmp packet
injection.  However, since I also tend to run ssh and ssl connections
on the same server (yes, I know it's a bad practice...) I'll have
to keep those libraries up to date anyway and it makes a certain
amount of sense to have the same crypto libs do everything.
