SubRosaSoft has released a free network monitoring utility for Macs, NetSpeedometer 2007.

The utility displays network performance and helps users monitor data going in and out of their Macs.

It's a Universal application for both Intel and PowerPC-based Macs, optimised to run at peak performance on both architectures.

The utility is available for free download and distribution, though the company is hoping users will donate a little money to the American Foundation for the Blind in exchange for use of the utility.
