I hacked up an ebuild for the mldonkey-desklet (based on some other, existing desklet-ebuild, forgot which I took). The mldonkey-desklet allows to monitor mldonkeys current up-/download rate and number of downloaded/-ing files. Don't complain about connection errors, when you forgot to set user and password, please!
Created attachment 23536 [details] desklet-mldonkey-0.1.2.ebuild
Before I even look at it, please include the Gentoo copyright at the top of the ebuild. Also, 0.1.3 is the latest version.
This desklet has been deprecated by recent versions of gDesklets.
