Need feedback on a couple website ideas.

#1 - YouTube video download site

I was thinking about the millions of people who visit the site and are limited to watching the videos on their computer. How cool would it be if you could bring those videos with you on your ipod (or other mp4/wmv player ).

I could offer a service where users visit the site fill out a form containing the url to the video and desired video codec along with their email address. Then the video would be downloaded by myself, converted, and uploaded to my server where they could download it and put it on their ipod.

#2 - Website search engine position tool

I googled that term and found no results for a tool that would tell people what position they were in search engines like Yahoo, Google, MSN, etc.

I would create a php script to do this.

Thanks for reading guys and I look forward to any comments you may have!
