[RSS and Facebook] Notify for new downloads

[Nabucco]

It would be very usefull a notification system when a new file is added.
The goal would be:

1) RSS
2) Mail notification (a workaround could be RSS linked to feedburner)
3) Autopublish on Social Networks (something similar to the joomla extensions to republish articles)

Just an idea, I think it would be really good.
Thanks for your work, Arno!

An automatic mail when a new file is adding or a newsfeed, that would be great! 
Maybe you do it Arno and I pay for this feature?
