Thanks, although, as I said, I haven't had that impression myself.

This one sticks out for me: back then (TM) there were terminals capable of some "forms mode" where there was immutable text and the back end just sent the content of fields. I don't know whether modern Linux terminal emulators (or even PuTTY,for that) can do this. One would have to look into that.

This might be something which up to now, your provider is doing for you (what kind of guarantees do you get currently?). Perhaps you need a new process in place you delegated to your provider up to now. Cheers -- t
