I've just had a look, but I don't know if I need new glasses or monitor, but when I went to download it for a try........it metioned that I need the dreaded 'windows'. Did I get it wrong? Fantastic bit of kit though.
kover is made for kde...you don't need windows. i think it may be your glasses :-) as there are only rpms or source packages available in the download section. after i posted the link i went and built it from source and it works perfectly. let me know if you have any luck.
