Interesting announcement from Opera today. Opera Unite turns your browser into an easy to use web server which can be used to shared stuff with your friends and family.
Neat idea, though I don't have my computer switched on all the time, so it's usefulness is limited to the periods when the computer is actually on.
The distributed approach is vaguely similar to Google Wave, but the details differ, of course.
The main problem I see with the approach is the limited upload bandwidth. I'm on ADSL, uploading stuff is slow, so having my meager upload bandwidth eaten by others is not what I want. Could be useful to people with fatter pipes, though.
Nice work, Opera. You showed them once again. :)
