I don't have this data in an automated way, but I was able to construct
a graph from the facilitator log. (The facilitator logs when a proxy
connects to it, but not the IP address, so this might be counting some
duplicates.)

Over the last three months it looks like we usually have between 20 and
40 proxies.

I too would like to be able to see this information in closer to real
time. The facilitator could accept a command to print the average number
of proxies over the last 24 hours, for example.

The facilitator code is not very complicated; maybe someone can make a
patch? It could be a new command like COUNT.
