[Sca-cooks] OT: Question about teapots

[lists at otcreations.com]

I'm thinking about buying a tea pot for someone (not on the list) for Christmas.  I was thinking about one of the nice Japanese iron tea pots 
and I'm having a problem between what I think the pot should hold versus what the ones I have seen hold.  This brought up a question for me.  
In your opinion, among the tea drinkers of the list, how much tea (in cups?  mugs? oz?) SHOULD a tea pot hold?

Curious,

Orla
