Abstract: A collaboration session is provided in which an owner computer system and a participant computer system are both members. Within this session, the collaborators are provided access to a multi-file workspace that is stored locally on the owner computer system. Initially, a set of development tools are identified. These tools are hosted by the owner computer system and are able to operate on the workspace's files. After the tools are identified, they are made accessible to the participant computer system. Later, a request is received from the participant computer system. In some instances, the request is directed to a particular file within the multi-file workspace and is generated using one of the development tools. In this manner, the collaboration session enables the owner computer system's development tools to become accessible to the participant computer system.
