The problem I see is some people want to profit from the good will of open source community.
I went to a ATA meeting there was a discussion of Web based Energy monitoring (user pays).
The guy giving the demo/talk seems to be chubby with hackerspace group and used some for developement of a power monitor based on Arduino and developed shild with zigbee RF link
The smarts connected to the Internet based on Open WRT Router.
Im very suspect when a for profit person seeking work/developement from a open source community.
If its for profit should not use open source, as it will distort the ethos of not for profit open source community.
At the end of the meeting i felt a bitter taste in my mouth, as you had to pay $$$ and to supcribe to the service you had to pay $20 per month for a web based energy monitoring service.
Ironic there is a better service from open source web based energy monitoring, than the commerical based one
