Johan mentioned to me that we could add videos to veven. Initally I tought it'd add a lot of complexity, but the more I looked into it the easier it seems. The simplest solution would be to expand the current image system to save images and then simply serve them with nginx and show them with the html <video> tag. This isn't the most efficent solution, but I think it's enough for a website of our scale.

Benifits of a custom video system includes:

• Custom video player styling (just think about it, A YELLOW PLAY BUTTON! so beautiful)
• More control over video playback (this could for example be nice on comittee application pages)
• All the benifits of storing images on the vev such as being avaible for viewing by future omega generations and associating them with events and people (this last one is too do)

Still, I think that an embedded youtube player would be good enough for most purposes, but this is an interessting project that I think would be appropriate for after release.
