To me it is unclear which software is allowed on party, and with that I mean giving you 0% chance of being banned.

Here's what I think is the current situation:
PE: NO
while not playing using PT to analyse your play: YES
having PT running while playing: yes
using PT to datamine (observing, not playing yourself): yes
using PartyMine v1.01: yes?
while playing: using PT (game time): no?
while playing: using PT and GT+: no

As you can see my list is rather incomplete and probably full of errors, feel free to add/correct information. Thanks.
