As others mentioned it def varies from state to state and I don't have any idea what the laws are in Florida. I'm in PA and I know here it is a violation to be drinking when serving alcohol, so it's possible that's the case in other states as well.
As far as homebrew clubs bringing beer in I'm guessing this only occurs when they are having a meeting or gathering of some sort and with permission from management of the bar/restaurant. These clubs may be paying a fee to be there or it may just be a courtesy of there's x people here for a meeting and ordering food and what not that they can share there homebrew between themselves. Certainly different than sitting down at the bar and opening a beer you brought in.
Legal or not common courtesy would be to ask management/owner prior to opening your bottle at the bar.
