We are using the WrapPanel from the Silverlight toolkit
Because we don't need the whole toolkit assembly, we copy/paste the source of the WrapPanel and use that.
Instead of the whole full blown assembly
Should be fine with the license: Ms-PL

“If you just need the WrapPanel, and don’t want to include the entire toolkit assembly, you can just paste these source files into your application project instead”
Sweet! Thanks Jeff!
