Hosting of WebCast Community

I am preparing to build a place to start the EdTechTalkK12 home. Anne Leftwich and I are looking at hosting a weekly (?) webcast that focuses more on K12 classroom practices. I can build a drupal on my Bluehost account or should I build one on the WB server. I want to be as connected as possible to the WB/ETT community but don't want to tax resources, I have appropriate alternatives. Jeff, when I asked before you said you were really neutral. If you are still really neutral, then I am thinking about building something that is a component of the WB/ETT world. I know I don't know or can comprehend all of this issues involved but alas I am awaiting enlightenment and planning on it coming in a day or two. ;)
