I think newsgroups is a great idea.. and a way I've been thinking it should have been done for a long while. You just upload everything at once and bam, they're there for a good 3 years on most good providers.
And the great thing is, it doesn't have to preclude other means of distribution. If an alternative means (such as the web-based mediafire suggestion above) etc. is found to be viable, it can live side by side. Again, the upload to Usenet is a one shot deal, and it's there for a good long time with zero maintenance. Other methods of web access can come up and be used with no problems.
If anything it's an excellent win-win with no drawbacks whatsoever.
