Silverlight is a fairly new plugin for your favorite browser (IE, Safari, Firefox, Opera) that displays animations, vector graphics, MP3 & WMA audio, and WMV video.  What’s cool about Silverlight:

• It’s quick
• Embedded text is searchable
• Works in conjunction with many programming languages
• Has a superior streaming video quality

As we make progress with Merchannex I will definitely consider utilizing Silverlight as a means of sharing content. The most beneficial feature that I see is that it makes your content searchable and indexable. Because my primary focus as of the present is SEO, this feature directly ties in and improves visibility on the web, if only a little. Every bit counts, right?
