Starting to look over the docs and I realize I might have just been able to incorporate the `optionsForClientTLS` into what I was already using. 

I was using `reactor.connectSSL()` with a default ``ssl.ClientContextFactory()` so I think I can make my own sslClientContextFactory with `optionsForClientTLS(hostname=host)` and pass that in to connectSSL instead.

It would look something like this:

reactor.connectSSL(hostname, port, MyProtocolClientFactory(), optionsForClientTLS(hostname=hostname))

I'll give it a try and play around with it.  If it doesn't work, I'll head back over to the endpoint examples.

1. You can't use connectSSL in combination with UNIX sockets
2. When we (one day) have a client version of the PROXY endpoint, you won't be able to use that with connectSSL
3. You can't do TLS-in-TLS tunneling with connectSSL for backhaul connections
