I think that this is an interesting concept, too, but like kits in 2E I think that 99% of the time stuff like this could come from straight role-playing and proper selection of skills and/feats. Sometimes, though, having a game mechanic as a "hook" for a character concept can be fun. In short, I look forward to continuing to see what people come up with.
That said, a comment:
I hope that this doesn't turn into a bunch of generic things like:
***
Bartender
The bartender tends bar at a local inn or tavern.
BAB: +0
Saves: Fort +2, Will +0, Ref +0
Class Skills: Alchemy, Bluff, Diplomacy, Profession (Bartending), Sense Motive, Knowledge(Spirits), Knowledge (Local). Skill Points: 4
Permanent Skills: The Bartender may choose any four skills from the above list to be permanent class skills.
Bartender's Skill (ex): The bartender can create spirits that have the effects of Sleep or Charm Person Spell (DC 10 + 1/2 Bartender's Character Level + Ranks in Alchemy).
***
That's really not the point. It's too generic and lame. Something like the Court Mage is a cool idea, though, that's not represented fully in the core-rules.
