I hope not... At least not until the BBS operators and writers agree
on some standardized API so people like me and other third parties
can write PC based interfaces in a language of our choice. The problem
with current "coupled systems" (for example the Coconet BBS software)
is that they all rely on proprietary interface programs on the PC. If
I communicate with 10 BBS systems (large or small), I must have 10
different communications programs... No thanks...

Also keep in mind that much of the value of these systems comes from
their availability to the widest possible audience. There are people
in many parts of the world who still have nothing better then 1970's
style glass tty's and even paper-output type terminals!

Back on the issue of privacy and anonymity, I don't understand the lure
of all these schemes for hiding mail paths, etc. If encrypted messages
pass through one aliaser, and get decrypted (and aliased again) on
another machine, you are protected. The machine that knows who you are
can't read your material, and the machine that can read you doesn't know
who you are. Any further obfuscation adds little (IMHO) to your
security. Revelation of your identity (in either case) depends on
collusion between system administrators on the different hosts. True
this might be even less likely where 3 or more hosts are involved, but
how much less so? If some agency is powerful enough to force two systems
in different parts of the world (and the net) to reveal what they know
about you, the chances are they can force three or four, etc.
