ive moved my entire development environment to cloud9 on a chromebook and i couldnt be happier with the performance and lack of overhead needed on my part. thanks!

Chromebook is actually what got me started as well :) Now it's also nice to be able to jump from Chromebook to Macbook to work computer if needed. Glad you're enjoying it!

Full disclosure: I am part of the C9 team

Its not lab grade testing, but there is the old standby https://dancesafe.org/
