How should I estimate how many concurrent connections I will have?
You can expect 1 connection per active developer and 1 connection per instance in each environment you have. Do be sure to run your Prefab client in a singleton object so you don't end up spawning more than you need to. If you are running in a language like Ruby that often uses multiple processes instead of threads you'll need to account for a connection per process.
