Contao and serving huge files

Hi,
I'm evaluating Contao for making a website that serves files to different protected memberships.
Contao membership fits perfectly.
My doubt is about file sizes: files for download are many and in particular some of them are .mov of 3 GB, audio files of 300 mb, pdf, apple keynotes.

Is it a good idea to keep all these files in contao website under the file manager, and serving them with downloads content element?

Better ideas?

Thanks

Davide

If you serve files via PHP (doesn't matter whether it is via Contao or something else), you'll run into the maximum_execution_time limit. The PHP script that serves the file will run as long as the user downloads, so if a User has a very slow internet connection, and your maximum_execution_time is not big enough, he won't be able to download the file completely.

I'm thinking about keep files in something like dropbox and linking inside my news... the problem is that dropbox files are public, so link are protected inside contao but not outside
