Not knowing all your other needs, I won't swear to it... but would the  
Juniper SRX650 work for your situation? It can pass 1.5Gbps of  
encrypted traffic according to their datasheet. I've never actually  
tried to move that much data through the box so I can't testify to it.

Also, the Juniper SRX3400 is advertised as handling 6Gbps of encrypted  
traffic.

Of course, these are JunosES devices as opposed to ScreenOS, but the  
transition isn't as painful as you might expect. We actually use the J- 
series devices with JunosES as site routers/firewalls with a great  
deal of success.
