Answer 1

There's now support for resumable uploads using CORS in the YouTube Data API v3.

A rough, but working, example at https://youtube-api-samples.googlecode.com/git/yt-upload-javascript/index.html (source files at https://code.google.com/p/youtube-api-samples/source/browse/#git%2Fyt-upload-javascript) that shows the upload flow, using the Google+ sign-in button to handle OAuth 2 (you can use the normal OAuth 2 browser client flow if you'd prefer) and with a progress indicator. It also shows how you could poll for video processing status following an upload and embed the resulting video on a page once it's been processed.
