I didn't have particularly high expectations, it was more "hey, why  
not try this, since I have a wrt54gs that's been sitting doing  
absolutely nothing for a year or so". Now its back to sitting around  
doing nothing. I seem to recall getting ~400kbps throughput with  
vpnc, 1.5Mbps with openswan (hooking to a Cisco vpn concentrator).  
The openswan number isn't terrible, until you consider that with  
something that can keep up with the crypto demands, I can usually  
move 10Mpbs+ over our vpn... :)

I looked into boxes w/IPSec crypto acceleration maybe six months ago.  
At the time, none of them ran OpenWRT and none of them were  
particularly inexpensive, so I just moved vpn duties onto a  
substantially more powerful system. If something runs OpenWRT, can do  
hardware crypto, and doesn't cost an arm and a leg, that'd be slick...
