An interesting alternative to SMS over XMPP/IRC over Twilio is SMS over XMPP over your Android phone. This lets you send and receive SMS on the computer and share the history with the phone. For this I'm using MAXS (http://projectmaxs.org/), an open source modular system available on F-Droid and Play store where each module is installed separately and provides a specific service over XMPP, such as receiving new messages, reading old messages, querying location, etc.

I can attest that this works well (I'm using it with the Profanity client), although the contacts aren't treated as IRC users. And a personal plan is much cheaper than Twilio.

Google has added support for this to their "Android Messages" SMS app on the playstore. They call the feature "messages for web". It's pretty slick actually.

I looked at MAXS once, but couldn't find anything about encrypting or signing messages, which kinda killed it for me.

I use JMP.chat but I'm not exactly sure it is what you are looking for.
