[DSFG] question: Custom hand written notice

[Jari Aalto <jari.aalto@cante.net>]

I'm preparing a package and would like to hear if this licence
(author's voice) is DSFG free. I intend to add this to
debian/copyright:

    License:

    The snow source code and the algorithms contained within it are free
    for non-commercial use. Licences for commercial single-customer
    applications will usually be granted free of charge, but contact the
    author for confirmation. 

    Notes:

    (*)As of 29 May 1999 the source code has changed from being public
    domain to being free for non-commercial use. However, commercial users
    are automatically granted a licence for any use of the snow code and
    algorithms deployed before this date.

Also in what section would this software go: main, non-free?
