Seadragon is awesome! I used it in a recent prototype, and our product managers were very impressed that all this could be done in html/javascript.

Now I have the go-ahead for a proprietary commercial product built using ASP.Net MVC. However, because Seadragon will be such an integral piece of the new product, we want to host the JS files along with our site. I've looked all over the Seadragon site for license information and found this previous discussion thread.

Its great that you came out with Seadragon in the ASP.Net Ajax Control Toolkit. However, we are building using MVC and aren't using any of the Microsoft Javascript libraries. So we only want the Seadragon portion of the that framework, and not everything that comes with it. We could strip it out on our own (BSD license), but that takes time and makes future upgrade difficult, etc.

Is there a way that we can host/license the files you host from Or is there a better way of using the AjaxControlToolkit version than I am thinking of?

Ryan, very sorry for the delayed response here! Hope this is still timely.

We generally do encourage going to the Ajax Control Toolkit version first, because it is officially supported by Microsoft and it is truly open source, etc. It's good to know that you considered this first.

We do provide the source to our standalone hosted version of Seadragon Ajax, but it is not under a fully open source license (there are some legal reasons for this which I'm not really an expert on). You have to remember also though that this version is from a "labs" group, which means we can't provide any official support (beyond e.g. this forum), and we can't make any promises of fixing bugs or shipping new versions. Heck, our group may not even exist in X months.

So those are the trade-offs. If you still want option B, send me an email; my @microsoft email is aseemk.
