Sorry, but you're wrong. You're assuming that computing power and  
user base will remain constant in 15 years. I can foresee the user  
base shrinking further, but on the other hand, if we had a mere 500  
or so PS3s onboard (and nothing else), we would already meet your  
estimate. This is using today's hardware, without upgrading it for 15  
years -- who can tell what will come along in the meantime.

RC5-72 will take long to finish, yes, but there's no need to exaggerate.
