Key word: universal.

That makes it hard.

Yes indeedy.

Too bad the infrastructure on the OS / client end of things is so shaky.
It seems like it takes a lot of work to set up and manage a CA, so that
the cost of setting up such a thing -- especially a reliable one -- is
really quite high.

Where did you get the idea that TCP/IP was universally convenient? :)

As I understand it, the backbones use ATM, clusters go to things like
Myrinet, embedded systems still rely on customer protocols over serial
links, etc. etc.

SLIP and PPP impose nigh-unacceptable overhead (I stuck with straight
dialup until I go go to broadband, as tcp/ip over a modem was
emphatically not convenient). . .
