VCMU aka Videotron Cable Modem Usage
What do you know: an opensource software has been available for ages, it’s pertains to my cable provider and I only learn about it now! It’s referred to as VCMU and is a registered project in SourceForge.
It really serves a very simple purpose: most of the plans on Videotron are limited in terms of up/down bandwidth, so this neat little utility connects with the Videotron servers and shows in graphical form where you stand on bandwidth consumption.
This is neat, simple, single-purpose and very well done indeed.
