Dunno - - - to me it sounds more like big brother is watching and
controlling.

I would be more than somewhat careful about siting stuff but I would also
not be allowing uncontrolled access to the internet. Unfettered access
means that someone else runs my system - - - that means I'm not really
the owner - - - which would prompt the question from me - - - if you want
to manage it that closely - - - I need to find something that I'm allowed to
run (get that 'stuff' out of here!!).
(I would bet that if their controller - - - especially the software - - borks
that you would still be responsible for the mess. That point would really
need clarification imo.)
