I just did a very cool test with the Miro feedreader this morning. Miro let's you subscribe to videoblogs and have their content delivered to your desktop automatically whenever new videos are posts.
I made up a videoblog with all of my mom's I Can't Open It videos
Each post embeds a YouTube video.
I added a feedburner podcast feed.
Then I subscribed with Miro.
I've got Miro set up to automatically download the most recent video when a new feed is added.
My mom's most recent video showed up right away and I watched it.
HA!
Isn't that cool?
For so long we were complaining that YouTube didn't have .mov enclosures and now it doesn't matter so much, at least for desktop aggregation.
I'm interested to see when we'll have access to YouTube's H.264 QuickTime encodes for delivery to portable media devices.
