thanks to solaris17 for pointing out eyeos to me. it is a cloud operating system that runs on multiple platforms. i have it running flawlessly under ubuntu 10.10. i had to do some php5 tweaking and had to make some changes to their settings.php file and i had to add a ton of different libraries and drivers ive never heard of but i got it to work nevertheless. essentially it is a tool for collaboration, a lot like google docs but with a desktop http://eyeos.org/ users can have their own private files and then if they want they can share them so others can work on them (spreadsheets, docs, images, music) just like you would in the office. what's even cooler is you can share your files to the outside world. for instance, i just shared a song and it gave me a url which i can link to anywhere. you can set a password on it and an expiration date. i highly recommend trying this out .
