 On answer is to move the session logging back one stage.  If you login from
some kind of PC with a terminal emulation program, you may be able to
cajole the terminal emulator to log the complete session.  (Recent
version of kermit on many different types of micro support this, for example.)

 As another choice, I suppose you could originally login in with a different
account, turn off talk, biff, etc, then invoke script.  From script make the
first command 'exec login', which should set up the right permissions on the
pty, add the utmp entry, etc.  Hopefully 'talk' sessions will then go through
your script session.  The price you pay is having to login twice.

 Of course you may leave the pty with the wrong ownership and permissions,
causing trouble for the next potential user of that pty.  And your entry in
utmp may not be properly removed.  I guess you can't have everything.
