I want to use Seadragon JS for a proprietary commercial product. Do you have any problem with me hosting my own mirror of your JS files or redistributing with my app? I didn't see any license or terms on the webpage..

For those who want to roll your own solution with Seadragon Ajax, we've got some really good news.

We're pleased to announce that a version of Seadragon Ajax is now available in source code as part of the ASP.Net Ajax Control Toolkit. This is distributed under Ms-PL, the open source compatible Microsoft Public License (

You can find the ASP.Net Ajax Control Toolkit here:

Because this is released under Ms-PL, you can do pretty much anything you want with it: host it on your own site, modify it in any way you choose, or re-distribute it with your own custom solution. If you come up with some great enhancements, you can also contribute back to the open source project on Codeplex.
