Sure you can.  The most common reason to do so would be a project told from the POVs of multiple characters: e.g. Chapter 1 is Harry telling the story, Chapter 2 is Murphy, Chapter 3 is Butters, etc...

Although I can conceive of reasons why you could still do so with only one protagonist...

My suspicion is that Jim usually needs thews when he's roleplaying. 

Oooo!

I'd definitely tune in for one that featured someone from the Donald Maass Literary Agency... Mr. Maass has some *damn* fine books on writing technique out there (I own two, and have made a point to have them in my store where I recommend and sell them regularly).  To say nothing of the other wonderful subjects they could discuss, I'd simply love to hear a discussion of "Writing The Breakout Novel" in terms of Jim Butcher's works in specific...

I believe Jim wrote Storm Front *before* having an agent, but despite that, I've always thought the Dresden Files are textbook examples of the advice Donald Maass gives to new authors in his book and workbook.  I'd also LOVE to hear Jim weigh in on how Maassively his writing has been influenced by his experiences with the agency.   

One man's magic is another man's science.

Not in the Dresdenverse it ain't--I'm pretty sure Harry would tell you magic is a distinct, defineable noun.

Awesome.  I'm also on board to help in any way I can.  

Absolutely can NOT tolerate it.

I'm really best off when I do my writing in a sealed, roofed, soundproof box.

Ooga.  I dunno whether I can do all of this or not.  I'll check, and hopefully have an answer within a day or two.
