Weblog Tools Collection ran an interesting review of VideoPress — a WordPress.com-hosted video streaming that I hadn’t heard of until the review.
VideoPress is a commercial Automattic product that you can enable in your WordPress.com blog. The cost is $59.97/year to enable VideoPress on your account. If you need storage above and beyond the 3gb of space that comes with your WordPress.com account, you can purchase additional storage: 5gb for $19.97; 15gb for $49.97; 25gb for $89.97 per year. There are currently no bandwidth limits.
Although the service is targeted at WordPress.com users, there is a VideoPress plugin for self-hosted blogs that lets users easily insert VideoPress-hosted videos into their self-hosted sites.
