I'm thinking plain old pairs-of-hex-digits might be the best

That's a lot less space-efficient than base64, though.
Well, base64 could give a 33% savings, but it's significantly harder
to encode/decode. Also, since it has a much larger set of valid
data characters, it would be *much* more likely to allow old-style
formatting to be mistaken for new-style. Unless we can think of
a more bulletproof format selection mechanism, that could be
an overriding consideration.
another nit with base64 is that properly encoded data requires
newlines according to the standard.
er, no, not as I read rfc 3548 s 2.1.
