I've opened a merge request that will both increase the polling 
frequency and bump up the max number of clients from 1 to 2 for 
unrestricted proxies. This change happens once the proxies have 
successfully opened a datachannel with a client.

Proxies that work well with clients in their pool already poll pretty 
frequently (once every 60s), so I don't think increasing this to 30 
seconds will make much of a difference, but doubling the capacity for 
unrestricted web-based proxies should. I'm hesitant to increase the 
maximum number of clients further without more testing.
