not really... it certainly keeps your ""command and control"" traffic from being
snooped by anyone else on the wire...

there is when you have to reconfigure the one device for the new network but
ok... most of the time there isn't... that's fine... this does provide a private
connection for all of your other traffic between the two devices, though... and
that prevents others from snooping on your traffic...

that was not really apparent but it is understandable... perhaps the venue has
another spare cable you can use? one that you plug into only your devices for
the private network setup i'm describing? either that or maybe directional
wireless but that brings its own possible problems to the table...
i should have noted that i'm also looking at this from a security standpoint and
keeping your traffic between your devices private and secure from others
snooping the traffic...
in any case, i've tried... you can try it or not... i'm not going to try to push
you one way or the other... with all that said, i'm out... good luck and have
