Interesting one this, I have played around with a similar idea for a club fundraiser and to attract new members. I thought about giving away samples rather than half/pints which limits the losses of giving away your precious homebrew for free, or alternatively charging a monthly/yearly membership fee instead. All the alcohol could then be given away free to members once the fee had been paid...
Didn't get an awful lot further on than that vague plan though!
