Err, no. Nobody else than us is working on this contest and pretty 
surely no one is going to start. RSA has canceled it years ago.

This is about cracking a SINGLE RC5-72 key, you know? It doesn't give 
any significant insight in cracking RC5 in whole other than what effort 
it takes to brute force ONE KEY. Imho, the effort should've stopped or 
been suspended once it became clear that we'd require more than 10 years 
(a lot!) to do it unless some serious advance could be made on the approach.

Just my .02
