Yeah thing is PlayOnLinux, crossover(codeweavers) and wine itself don't actually work, you can install and open but it often bugs out with the flash plugin. I know this is practically necro just noting the wall I hit.

The only chance is if it gets rebuilt completely with a different flash player (Ex. pepper) doing so would not be worth the time and effort as there is already enough variable assumption to make the current mini client run on windows, I cant imagine the nightmare of essentially doing a complete rebuild port for a OS that isn't really mainstream.
