I'm well aware of what you're talking about Xargos - indeed in my country. the "weird wired world" as Times magazine puts it, many of the population is hooked to internet provided gambling which doesn't even use real money, and use only game money.
Now it's cut out to be a social problem because youngsters pay real money to buy game money - and people being so sensitive and addictive to such gambling game became a problem.
However, I don't expect it to be a such a large threat in AH. Luckily most of the gamers of AH are more or less adults, and hopefully they have more brains than to waste real money to buy 'perk money'.
Also, some measures may be taken by the staff to limit it - like perhaps a total limit of earnings or losses set by Perk Poker.
Also, making it more than just a gambling den, perhaps a place where people can transfer limited amount of perks to their squaddies, or exchange bomber perks to fighter perks and etc.. might stay people from turning AH2 into Vegas.
