Chimera last I heard was not open source or freeware (ie: its commercial.)
Specifically, even if a developer got it for free, he'd be hostage to it.. which may be fine for some.
Being closed means you depend on them porting and maintaining it;if they release an ARM linux binary, it 'might' work, but probably not ideally. Talk to them.. since its not open source, no one can help them.
