I'd also contribute in some manner to this. Like (what I assume) most people, I don't have the time to take the lead on something like this I would help in any of the following areas:

1. Technology. Getting the RSS working...whatever.

2. Moderation/hosting. I've not spent any time doing a podcast, but I do have a decent public speaking ability (funnily enough obtained by being raised in a religious organization that trains in that), and a good ability at helping others break their arguments and explanations down to a layperson's level).
