Desaware has just announced that they are, in addition to bundling their products into two separate suites (.NET and COM versions), including FULL SOURCE CODE!!!!!
This is incredible news. Considered to be one of the companies that pulls off the impossible with their products, you can now see exactly how they managed to do it! Also, combining the products into suites is pretty cool as well.
[update] There's also an interesting white paper they have on their site concerning this shift titled Impact of Source Code Availability on the Economics of Using Third Party Components in pdf format.
