This is something I am looking into aswell, because I will be buying a Chromebook for school soon.
I don't have any experience i Linux, but I believe there's Le Bot 7.7 for Linux somewhere on the forums.
Sadly missing out on Carbon and Cetera.
@D.V. said he was going to release the source code for Carbon a while ago, and I believe you could recompile it to work with Linux.
Wine may work, if not, a VM will work.
