I didnt see your post on Facebook as I am not on much on the TAW Facebook. As I posted on my doc proposal, the idea is to use NAP and blue status instead of alliances. And yes, diplomacy is a very big thing, absolutely. I have a list of corporations/alliances to talk to regarding NAP and blue status.
1. Regarding spies, compartmentalization and need to know basis is the answer in my opinion. It is true that strife can be caused over a number of years, however that is really true for any games in TAW. I wont go in details, but I have been told stories of other games where the wrong leadership/access took the game down. So it is not an EVE issue only.
2. You are referring to high sec. Corp will be based in NPC null, out of a NPC station, within jumps of sov null. So PVP will be constant and good luck to any high sec pilots coming over to our area. And as far as wardecs:
a) today's update if I recall correctly has banned high sec wardecs for any corps without structures. But again, that is of no concern because corp will be based in NPC null, in an NPC station.
And again, PVP will be constant and will be part of life and growth of the corp.
Regarding your last point, as I mentioned in my first point, it is an issue for any division. However, I also believe TAW has strong checks and balances to limit such a risk and with the additional EVE check and balances used by EVE corporations, I believe the risk in question is mitigated.
