Converted my home automation server to SSL, valid certs and all. Been slowly doing that to all my boxes. Browsers are getting annoying with giving warnings on forms, even for local sites and I hate dealing with SSL warnings, so went all the way. It's nice to see things being more "clean". No warnings etc.
The biggest nice change has been my dev server, everything is SSLed now. The warnings on forms was getting irritating to deal with. I use an internal sub domain that is valid online, so I can do cert validation that way. There's a cron job that just fetches the cert from the web server and puts it on all my local servers.
