i propose a windows movie maker "publish to..." powertoy for the channel 9 team. basically, right from windows move maker, anyone at microsoft could publish to the site, quick and easy, lots of new (and odd stuff).
of course, then later, release it to the public so anyone can publish to any blog. it would generate an rss item based on the size, movie info and stuff i'd type in movie maker. it could be make to work with all the blogging tools, or just have it open to other blogging tools can make plug ins for it.
