1) use Google Chrome (current flash version is 11.5) (~60% of all our Linux users are using Chrome)
2) there is a way to use 11.3+ for Chromium: http://www.webupd8.org/2012/09/how-to-make-chromium-use-flash-player.html
3) an Arch-package is available: http://aur.archlinux.org/packages.php?ID=60443
This is all the information I have specific to Linux
Can not do 1) and 2) because can not install Chrome on Ubuntu 10.04. And can NOT update Ubuntu because my boss will not give me the admin pass
3) - dont know what Arch is.
