question: how about making the authentication step a separate external
program that returned an exit code of 0 or 1 to indicate successful
authentication (and perhaps other error codes to indicate temporary
failure, etc)

and then cvs could come with a few programs that you could plug in;
one for regular passwd, one for pam, or write your own?

for security, you obviously don't want to send the user/passwd on the
command line, but how about as writes down a pipe?

Not sure how well that would port to windows, though.
