PartyShare is an app for Mac and Linux(Windows too) that utilizes the IPFS protocol. It allows users to share files using IPFS. You simply drag the file you want into the PartyShare folder and hashes it/assigns the address for you. Your friends can then request the file using the address you gave them it's that easy.
Did I mention it's completely free? Yeah for real WTF. Of course there will be issues you might come across but this is just the beginning of apps to be made for IPFS.
