upload large files in the Wiki

[Nicu Buculei]

Recently I polished some floating heads for Planet Fedora and I 
privately got asked about tome tips on the subject, so I wrote this: 
http://fedoraproject.org/wiki/NicuBuculei/Hackerogotchi

It seems my short tutorial was not clear enough, I was asked for a more 
detailed description, so I made a screencast. Which leads me to the 
subject of this question:

What is considered acceptable use for uploading files on the Wiki? How 
about a 13 MB video file in OGG Theora format? Also, how about hot 
linking? Is it forbidden or tolerated?

nicu - still frustrated by the experience of making a screencast: 
Istanbul and Byzanz crashes, had to eat crow and use Flash and transcode 
it later to Theora
