    Don't ever say NEVER or CANNOT.  Just doesn't work when dealing
with computers.  Tim Purves' BBS versions 2.0 and up can and do
work well when the same file is accessed by two tasks on an ST.
    While a user is logged onto the ST, accessing a file (downloading),
another user, or even the SysOp can access or download the same file.
No crashes, no bombers.  It just works.
