The bill has passed it's first committee 18-0, next is appropriations, then, if I'm not mistaken it will go to the senate floor. Given the narrow focus on the bill and the widespread support it had on the Government Organization Committee, there seems to be optimism it will pass the appropriations (it's not going to cost anything and that's generally what they're concerned with) and will pass on the floor.
The fact they were asking for people to buy memberships in order to gain entrance what why it was deemed as "selling". The fact that they ask people to donate beer yet still charge them is more of a pr thing and every non-profit has to make those decisions. I'm on the executive board of a local school district non-profit, and we don't give free golf tourney entrances to our contributors unless their contribution exceeds a certain amount. Given the throngs that want to brew (we won the BRO contest last year...Santa Barbeerians!!!) and bring it to this festival, I doubt free entrances to the beer donors is ever going to be in the cards.

Press release on the new bill.
Edit: I just reread your post, and I'm not sure what exactly you're asking me, or how exactly to answer regarding homebrew clubs. Most homebrew clubs are not 501c3s so I don't think these laws really change anything for them. But you are certainly referring to an area of the law that's subject to interpretation, so if anyone online asked me what I thought of that I'd probably refer them to an attorney...maybe there's one on the club already?
