Richard, you're dead-on. With POD so many walls are demolished. The problem simply becomes one of marketing what thoughtful, innovative, and passionate authors/artists have already created vs. the financial decisions on whether to produce something in the first place--and marketing, while always challenging, is doable largely using word-of-mouth on the Internet. Great examples (in addition to Judge's Guild) are the indie games produced today: some really great, innovative stuff that would never have seen light of day before POD. Not that I would suggest doing away with big corps (like WOTC), though, for their financial power affords them the ability to create some amazingly high quality stuff (if limited in scope and set to the lowest common consumer).
PS: Cool on the deal with gameprinter! Something to look forward to!
