The LaCOLLA middleware makes it possible for collaborators to interact using their own resources without depending on centralized regimes. By contributing their own resources, group members can organize and communicate using a federated peer-to-peer model. This lets the group function regardless of whether a member removes resources and despite network or node failures or disconnection. In turn, this capacity for self-organization, together with location transparency, lets application developers create self-sufficient applications for collaborative activity.
