Then someone should not do it for free.  They should do it as a "data
recovery tool", advertise widely, make a few bucks, and show what a piece
of crap the IPG snakeoil is in the first place.

Cracktools are starting to become a profitable business as more and more
snakeoil products appear on the market.  (Most are marketed to law
enforcement, but that will probibly change...)

There is a buck or two to be made here.

There's probably more money to be made by blackmailing the snake-oil
peddler (pay me so I don't release the cracktool for your crap) than
by selling the cracktools themselves.

That is impossible, it is self evident that it cannot be done. There are
some people who are trying to break it, but they will obviously find that
is impossible.

Give up, no one can break the IPG system. That is a fact, not an opinion,
like some of the cypherpunks.

With kindest regards,

I've been *very* busy lately and have not had a chance to examine the IPG
system with the level detail it deserves. So far I haven't seen any weaknesses
discussed on this mailing list. The above quote does NOT refer to your system.

Your both right.
The correct approach is to blackmail the peddler, and then sell the
cracker after the peddler has got enough of the product out there to make
your sales significant.

In this day and age of throw-away identity, you can make money coming and
going.
