[PR] Fluid piping 2, lets do this again

[Cheese]

I aint no chemnerd, and while I am willing to become one if that means messing with pipes, can't really add much to that side of the discussion.

But whatever heinous concoctions people will produce with this - they should be relatively easily deliverable on site and, more importantly, monetizable. So... Having metered spigots, possibly wireable to payment components, would be cool.
Maybe some thingamabob that accepts a mug/flask/whatever and allows one to get a measure of the vile brew - within amount limiters set by the chemist. Very hackable, changeable limiters.
