They released it in bottles, but it was severely infected and recalled so don't bother trying to trade for one of those. Can't help you on the other questions, unfortunately.
Thanks, seems that there are a lot of good reviews recently and I haven't seen it on the stone bottle or draught list..
they seem to have kegs of it on hand that they ship to special beer events. I had the '08 Stone Bourbon IRS on tap at a barrel aged beer event in Cincinnati last Winter
Had and 07 BA RIS and its was fantastic, bourbon nicely integrated and smooth. Great stuff, I went back severasl time to polish of the keg. But to answer you question, it does get distributed for special events and such.
