originally i wanted to use linux, but the screen tearing there was even worse.

i think there was a demo with piezo microphones on a wall or chipboard, but i'm not able to find it.

i've thought of a case i used a regex the last time. and it was removing whitespace in some code file.

if it's about collaborative working on a long text: perhaps plain text-files and a version control system like git is the way to go?

if you want to discuss about a medium-length text, you could use a etherpad.

http://etherpad.org/ - example: http://piratenpad.de/p/hackernews

- good documentation

- many small examples you can start from

- all built in (video/sound/grafik)

- you can extend it by using java
