Maybe version 0.5 would work with lossless and version 2.X would

However long is easiest I suppose. 1 sec? 10 sec? Repeated in
spots through the file X times, where 1 < X < (length in minutes)?

Maybe version 0.5 is 10% chance of proving, and version 2.X would be
better?

Some operations would be:

- Mark
- Un-mark
- Re-mark
- Remove
- Verify signature
- Verify content

In a later version maybe the tool could be able to use some of the
above tools, in cooperation with other sound file tools, to preserve
a watermark across sound file format conversions, between lossless
forms and crossing between lossy/lossless domains.

For version 0.01 even just being able to attach an md5 sum of an
audio file along with a gpg signature would be cool.

I use a subset of GNUPG's capability. Maybe you can see that in
my above requirements? ;-)

Is that a useful start on a start?

Thanks....
