Boy, I'm glad that, when you faced the much smaller problem of 
non-ASCII
subject lines back in 1991, you and your buddies decided to ``maximize
the rate'' of deployment by inventing your own encoding mechanisms,
rather than giving in to the demands of 8-bit transparency. Oh, sure, 
we

you could *NOT* trust that all the systems
between here and there were 8-bit-clean (in fact, an 8-bit-clean system
was a rarity)

In fact, in 1991, you couldn't even rely on them being 7-bit-clean.  I 
remember exchanging mail with someone whose mail server kept changing ^ to 
? for all messages he sent or received.  (It came up because we were 
talking about Pascal.  I was young, OK? :-) We eventually figured out 
that, although he had an Internet-style address, his mail gateway was 
connected via BITNET, which used EBCDIC.  That's where base64 came from: 
it had to use characters that would be legal in all known systems.
