Currently, Ethos is focused on plugins for applications written in C or Vala since they provide the common denominator to enable the largest variety of scripting languages. However, that's not to say you couldn't provide a thunk layer for something else.
I'd like to thank the giftwrap hackers for helping me dog-food and get ethos ready for an initial release.
