This is an incomplete starting point of making an Adium plugin wrapping https://github.com/matrix-org/purple-matrix which I just found lost in a workspace on my laptop.
It looks like it was a few hours work, scavanged from https://github.com/edom71/microblog-purple/tree/adium-merge (then on http://microblog-purple.googlecode.com), which got as far as setting up the basic shape of the project but then no code to actually link or wire in purple-matrix.
It does not work, and needs someone to finish it.
It should probably also live in an /adium subdirectory of purple-matrix but I'm not going to check it in there given it's totally WIP.
