Hello Michel,

What telnet transition? Telnet is just another way to get a connection into a 
BBS.  I imagine that on many systems the BBS software does not even need to 
know that telnet is involved, it's just another tty.

After reading this paragraph several times I /think/ I understand what you were 
trying to say. If you try to use English more simply, you may end up with more 
readable results (this is something that I have to remind myself at times too).

  MS> I'd make the UpGrade Path INCLUSIVE.  I'm thinking of a scheme
    > like ~POP3~ before ~SMTP~...

Please explain that. Do you mean that you would have the user retrieve messages 
from your BBS using the POP3 protocol, and post their replies via SMTP?

  MS> ...but with a twist;  i'd keep ~TelNet~ but require my LEGACY

That would not work for the many, many people who are assigned IP addresses 
dynamically (not just dial-up users, but also many DSL customers).

SSH supercedes telnet for applications where security is a concern. Combining 
them is odd.

Why reinvent the wheel?
