Yes, I think!

I've got in touch with seroperson. Luckily, he was able to find the sources and he still doesn't mind to share them. So here is the new github repo: https://github.com/Cor-cor/tmediator

However, the code is a bit outdated. I've made a hotfix to get the main thing to work again (no globals yet). Link: http://sabercathost.com/Zct/tMediator-0.14.1.jar

And I'm willing to maintain the project (in a broad sense), but not sure which way. It would be either fixes to the existing codebase or just rewriting it altogether. I'm not a huge fan of Java actually.

In any case, stay tuned!
