A few days ago Duncan added support for embedding Soapbox videos into a post in the Channel 9 forums using this simple BBCode style tag:

[soapbox video="(soapbox video id)"]

Very nice and simple.  And as he mentions in his next post, I bugged him about adding a tag for Silverlight Streaming Apps.  Working tirelessly through the holiday weekend, Duncan has now added the requested tag.

[silverlightstreaming accountid="32" appname="sllogo" width="258" height="100"]

More parameters but also more functionality as a Silverlight Streaming App can be more than just a media player.  Looking forward to see where this goes on Channel 9.
