App request: Video search engine app!

For now, the best solution to downloading youtube videos or videos from other video sites and playing them at a good quality is by copying the URL of the video that you want to see, pasting it at keepvid.com and then downloading it straight to your memory card/phone memory at high quality. There is a thread already on this and this tip has been great. But it's still a hassle.

I was wondering if someone could design an app that would somehow automate this process. I know there's vuclip but I think this would be better. No streaming. Just direct downloading at high quality by using keepvid.

This would be great and I know a lot of people would love it.
