Audio Sky Tours: An Example and Questions

I've completed an audio program about M13 The Globular Cluster in
Hercules.

It is short and not too professional. However, it is certainly
suitable for listening while viewing the object in one's telescope.
(This is my intent.)

I would like to place it where others can improve upon it, as well as
create similar audio programs. I am thinking of the wikipedia.

I would like advice on copyright issues (the music was obtained under a
creative commons license,) where would be a good community based site
to do this project, and critiques of the program itself.

The whole podcasting phenomenon got me thinking about using these ideas
for astronomy. I think the sci.astro.planetarium group may be well
versed in some of these issues, but will be cross posting elsewhere as
well.

Thanks!

John
