I don't see a problem as long as you do NOT use TELL. Creating a list is
something "important", you can't afford losing one of the parameters
because a link went down. Another thing is that most people don't have
access to TELL. So what you want is a program that asks questions and
prepares a list header, then mails it to someone for processing. This can
be a human being or a server that would check everything and issue the
PUT command. The problem as usual is writing an interface for 200
different environments...
