How many plants per pot?

[horsebones]

Going by this image, it looks like there are 2 very close plants in this pot, or the plant was pinched very low. If this is 2 plants, do you recommend growing more than one per pot or does it depend on the species?

I have a few "twin-chiles" growing this year. Two plants in one pot. The pots are quite big though. I have twisted the stems around each other and they seem to be doing ok! I think I should upload some pics of those twisted stems to my chile-diary on the Finnish section of Chilifoorumi. So stay alert! 

EDIT: Here's my latest update, including two twisted chiles. Those stems will make a nice bonchi!
