Well lately using leopard azureus has been giving me plenty of kernel panics and I never could get any speed out of transmission due to my ports always being stealth or blocked even when I forwarded the ports. Then when I was reading some forums I stumbled across this, downloaded it, and now transmission downloads just as fast as azureus if not faster, my ram isn't being used as much and no more kernel panics. plus the port is always open. I give this a 5 out of 5 stars.
