Sad day. Today i failed.
A customer pushed my boss to use #skype for a meeting.
I showed him #Jitsi: no installation, no accounts, just a link to share, same features (we will use it just for desktop sharing, calls will be via phone because we don't have microphones/headphones/speakerphone connected to pc).
This morning he made me create a skype account and share with the customer.
Damn.
