kMule
A really small ed2k client without bloat - downloading at its best!
kMule - short form for "kad mule" - is intended to be the most lightweight eMule compatible client out there. While eMule does a great job, it may contain too much bloat for the everyday user and it's updated not often enough to respond to the users wishes.
That's where kMule comes in, it's basically a barebone "mule", designed to run unattended.
