Sounds kinky to me.

4. This is actually a very famous problem in fair division theory!
Say that the three are A, B, & C.
Allow A to pour a portion of the bottle into a glass.
Now B has the option to decrease the amount by pouring some from that glass into another glass.
BUT B has no obligation to do so, B may pass.
Now C is given the same two options.
The last person to touch the first glass gets the glass.

Now we have a partial bottle or a partial glass.
Now you are back to a two person fair division.
Let them divide the remains.

5. Sounds like something John Nash would be interested in.
