Thanks for your comments; glad you like the way we integrated it!

No, as it turns out, SAN makes the auto-management code highly complicated, since names could overlap in different certs, etc. It also complicates renewals and gives more room for error (e.g. 49 of the domains verify but 1 fails, so the cert can't be renewed). So I've opted not to support SAN certificates for the automatic HTTPS feature. But you can of course still issue your own SAN certificates and use those.
Right now, Caddy reloads itself when it renews certificates, but as of Caddy 0.8.2 (slated for release any day now), Caddy will do it all in-process, no reloading.
