Easy solution. Make the more sophisticated algorithm routine. Make it
modular, so RSA or IDEA can be easily replaced if needed, later. I
thought I read of some standards being worked on which incorporated PGP,
actually. Building Vingere ciphers into TCP/IP won't help much;
building in RC4 would. If this would be inconvenient, well, maybe it's
worth it. Besides, predictable improvements should last long enough so
that continuous encryption is fairly feasible; those same improvements
won't help NSA or criminal crackers one bit. Well, some bits, but not
nearly enough.
Fantaside:
I want fast symmetric kilobit-key encryption. Search space of 10^300.
10^100 particles in the universe, each a hypercomputer running at 10^100
attempts a second, given the age of the universe (10^17 seconds) would
be worthless. Bwa-ha-ha!

Actually I was told that RC4 _isn't_ totally white; that the cypherpunks
et al. were gleeful when this was discovered "Ha! This will show RSA
Inc. to allow public criticism!" and were subsequently confounded when
the skew in the output proved to be almost worthless in helping to break
it.
Rudi made RC4 sound very weird.

} Nope. That's a totally naive statement.
Did seem a bit extreme, I agree.
