I've forked this and added the ruby and bash versions of rmate as subrepositories, it took me a while to realise there was no client app included in Henrik's repo. Good work, though!

There's no need to "install" it on the remote server, you just need to copy one of the rmate files up and run it. There's plenty of detail on the web about how to do that already.
However, I have added some text to the README about installing the Sublime Text part locally. As I only have access to Macs, it's got a decidedly Mac-centric slant, but hopefully people on other platforms can tell me where the files are located on their OSs.
Readme is visible in the GitHub repo: https://github.com/Drarok/rsub
I thought I'd opened a pull req and it had gone unnoticed. Turns out, I forgot to create the request! Created one now with a (hopefully) detailed comment. Sorry.
I wrote a blog post with detailed instructions how to get both local and remote parts working, took me some time to get everything figured out: http://danieldemmel.me/blog/2012/09/02/setting-up-rmate-with-sublime-text-for-remote-file-editing-over-ssh/
Idees
It's still kinda buggy, but it works.

Awesome fork by the way.
