You're welcome to do this for free, but the following could be a money-maker for you and fill a real need...
What if you made available the ability to sign-up for subdomains on SafeShare? Here's how I see it:
1. Each school/business would have it's own subdomain (e.g. harvard.safeshare.tv). This would allow school filters to whitelist content from/to that subdomain while blocking the main site and other subdomains.
2. Those generating SafeView videos for a safeshare subdomain would need to be securely logged-in, and each school would have control over which users had the permissions to generate SafeView videos. Ideally, these permissions for SafeView generating could be synced with already created groups of teachers in Active Directory and Google Apps. Each generated SafeView page would also list the generator, providing further accountability.
3. Within each domain there could a Browse section where teachers list SafeViews by topic; these SafeViews could also be searchable by teachers who are logged-in to their subdomain.
Thanks for considering this!
