the alternative could be so that a proggy (maybe cotobo?) would automatically send a packet containing your WH pass right after you log in...
but then we have the "bjx steals your acc and pw" thread all over again, only this time it would be cotobo and just the wh pw

(i'm not saying that choco would steal your pw, but the majority of ppl are paranoid :P)
but imo it's pretty pointless anyway, maybe usefull to the lazy ppl :P
