Are your friends talking microbrewery or brew pub? Your questionnaire gave me the impression of a brew pub, which is a completely different animal.
I got the impression from them that brew-pubs had even more problems: Can't sell off-site, must have at least X% of sales from food, competes with the restaurant scene, etc.etc. Because of those laws and the restaurant competition, they are trying to do a brewery.
Does anyone know if the legal restrictions will change at some point? Are there any laws in the works? Georgia has one of the lowest breweries per capita in the US.
Brew pubs would have some issues, much along the lines of what you've mentioned here, but based on the number of brew pubs versus breweries, I'd bet that brew pubs would be easier from a regulatory standpoint.
Georgia does have one of the lowest number of breweries per capita, and from what I understand, it's largely a result of the restrictive laws. Ask me a year ago if that would have a chance of changing and I would have said no way in hell, but I would have said the same about Sunday alcohol sales, and look what happened. I definitely think it's possible now, but it's gonna take a concerted effort to overcome the distributor lobby in the state legislature. That said, Atlanta is really becoming a beer aficionado's destination, with the key missing piece being a strong local brewing contingent.
If you're serious about this, I'll echo angryuser's suggestion to talk to Crawford over at Five Seasons. He can give you a first-hand account of how these laws killed his business.
