SandDock for Silverlight – Commercial floating windows
Every once in a while you see something so promising you just have to pass it along. The folks at divElements are developing SandDock for Silverlight; a floating windows management toolkit that looks very sweet indeed.
I can't say I've really put it through its paces, or pushed its limits, but there is a very professional feel about the work they've done so far, and I suspect this is a product worth keeping an eye on -- especially if you happen to need what they have on offer. From what I can tell, they're in (free) Beta now, with a product on the near horizon.
There are of course a number of great third party tool makers for Silverlight, the interesting question over the coming months will be whether folks will turn to buying their tools or creating them from the fundamentals provided by Microsoft and the Toolkit project.
