Tommy - having been in the Navy when I was young I can tell you that story is very true - for around $5 you could live like a king in some places with whole stables of women waiting on you for a whole weekend - for whatever you want. Of course I never did anything like that
As far as the ID for porn suppliers on the internet - it will never happen - just like the .xxx idea - the FRC and other groups from the religious right will yell legitimicy - and the congress would step back not wanting to offend their constituency with giving porn the "status" of acceptable.
