A few days ago I blogged about the trouble of getting Credentials to work in Silverlight Networking. The troubles still exists sadly. I've been thinking about creating a simple Silverlight application that makes use of the del.isio.us API. But sadly this API, as most of the online API's do, makes use of Basic Auth over HTTP or HTTPS. I have thought about many different Silverlight applications that makes use of online API's, but sadly I wasn't able to create them because of the lacking of authentication possibilities. But I just got an idea, by thinking out-of-the-box. I might just get out of this very limiting box. Although it's just an idea that's not tried out in the wild.
