Excellent podcast. Packed with great info. I learned a lot but was most excited to hear you talk about using the DLR and languages like Ruby outside of Silverlight. I'd gotten it into my head that using one required the other. Not true. Nothing at all against Silverlight, but being able to run Ruby inside of a DLR implementation of the Rails framework (which will no doubt come along shortly) while having external access to the .NET framework... Holy cow!
