What does W7 in 'W7 stream cipher' stand for?

    The W7 is a stream cipher or a key stream generator. What does W7 stand for?

    Here's the original paper:
    https://tools.ietf.org/html/draft-thomas-w7cipher-01

    So maybe it is W for wave and 7 for its bit length ##2^7=128##. But more likely is, that it is due to the fact that two main authors (Thomas and Anthony) did their research under Wave7 Optics Inc. (cp. http://www.manta.com/c/mbyckx0/wave7-optics-inc and http://www.techonline.com/directory/wave7-optics). Maybe both sevens are of the same origin though. However, it looks a bit like a thing of the past.
