100 peers in the same room for PUN

Options

Hello, we are making a mmorpg testing demo and would like to have at least 100 peers to be in the same channel/ room at the same time. There will not be much action, and it is a 2d game with just chat and motion function implemented (no fighting or anything like that). However, it is showing that only up to 16 peers per room, is there any other option for that? I have emailed to the support few days ago but got no reply.

Thanks ahead!
