I'm not sure if this is what you meant though, but you can upload your video onto http://www.yousendit.com

Send the file to your own e-mail address and you'll receive this link that you can post on here. Everyone just has to click
on the link to download the video. They only have 7 days to download it though because YouSendIt has to delete it off of their site to make more room for others to use.

My friend just told me about this site earlier today so I tried it out and it works! Good luck!
