1. A method for connecting a secure peer-to-peer collaboration system to an external system wherein each collaborating member uses tools within a local shared space copy to update data therein and collaborating members securely exchange data between local shared space copies, the method comprising: (a) installing a service on a server external to all of the local shared space copies, the service including service code for exchanging data with the external system and a designated tool; (b) causing the service to join the collaboration system as a member so that the collaboration system replicates a copy of the shared space on the server; (c) scanning the replicated shared space copy to discover tools therein; and (d) using the service code to exchange data between the external system and the designated tool when the replicated shared space copy includes the designated tool.
