SEAL cipher info requested (something actually list related!)

Anybody have info on the SEAL cipher?  I can't find any
descriptions or analysis of it.  Refs, proceedings or URLS
would be a good thing.

(It isn't related to NSEA is it?!?)

I also am interested in references to it.

I'm told that it was invented by a cryptographer at IBM, and that it
patented, so that should help in the search.

Its a Don Coppersmith creation. It is blazingly fast. I believe it is
patented.

I believe it was presented at the first Cambridge security workshop on 
fast software encryption.

Correct.  The paper is "A Software Optimized Encryption Algorithm", by
Phillip Rogaway and Don Coppersmith, pp 56-63 of the proceedings.

It is a fast stream cipher.  The paper reports encryption rates of 7.2
MBytes/Second on a 486-50.
