Yeah.  I wanted to see some takes on this, albeit nothing outrageously important or revolutionary.  Thats why I called.  Hence, i'm glad to see that that call was so promptly returned!  huh.

Nonetheless, I think you summarized it pretty well on the blog.  Yeah, i think there would definitely be some areas where there could be some fulfillment but it would be limited in scope to either companies that aren't so great at providing replacement parts, obsoleted games or older games in general.  Its not a for profit scheme as with most niche stuff.  It's one of those things where it would be cool if someone did it if ever there's a need for a part, but not capitalistic enough for people to actually do it with economic incentives. 

(And yeah, the truth of the matter is, the time that must be spent, mailing, organizing, and details would negate any possibility of the ludicrous profitability).   But it might just be fun.
