There are some things that aren't time sensitive (i.e.: blueprints, long 
term plans, relations).  Also, if they have about $50,000, then they can 
build a 64 node Linux cluster utilizing AMD Athlon processors.  That's just 
as powerful as some $21 million super computers.  So, you don't need a 
"**** load" of money to get a lot of processing power.   Okay, okay, it 
seems like a lot to us, but not to some one/thing that has millions or 
billions.

And yeah, AES might take to long, but it won't be long before we can crack 
that code in 22 hours as well (under ten years.)  I haven't seen anybody 
mention the 64bit processor development.  Intel already has 64bit 
processors, and AMD is developing theirs and should have some available by 
2003.  Of course Intel's 64bit processors are aimed at the server market, 
however, AMD's is aimed at the home market.

I've herd the Dnet staff make mention about 64bit encryption fitting nicely 
into two 32bit registers.  Correct me if I'm wrong, AES is a 128bit 
encryption process, so it should fit nicely into two 64bit registers.
