Part of the point I'm making is when you use the term "need", as in 
"need to check" and "the need for this", you are actually referring to 
PLT's "need", not to the user's need.  At best, you can speculate about 
what *you* think is in a user's best interests, but ultimately, what the 
user thinks is what should count.  If you're taking the position that 
no, it's your opinion about what the user should want that counts, don't 
be surprised when your users don't agree with you.

Any solution that does not involve explicit permission from the user 
prior to making a connection is unacceptable.  If you don't understand 
that, you're not listening to the objections that are being made.
