Hi all,

	I researched on this area for sometime. I have made some testing using 
site-to-site tunnels, and for sure, blowfish is the best relation 
between throughput and CPU utilization. Other things that is very 
interesting is that with  blowfish, no matter what the the key size is, 
it works faster than other algorithims in software and in hardware(using 
same specs hardware) with the same key size.
	But people does not use it very much because it is not the NIST
