If raw speed is needed (N.B. I'm not addressing security here), have you
considered the Panama stream cipher? It's reported to be twice as fast as
SEAL, or six times faster than RC4. This should be more than eleven times
the minimum speed you mention above. As a bonus, Panama also works in a
256-bit hashing function mode.
Panama is described (and its security is assessed) in J. Daemen and C.S.K.
