We designed, developed, deployed, and evaluated theCollaborative nanoManipulator (CnM), a systemsupporting remote collaboration between users of thenanoManipulator interface to atomic force microscopes.To be accepted by users, the shared nanoManipulatorapplication had to have the same high level ofinteractivity as the single user system and the applicationhad to support a user's ability to interleave workingprivately and working collaboratively. This paper brieflydescribes the entire collaboration system, but focuses onthe shared nanoManipulator application. Based on ourexperience developing the CnM, we present: a method ofanalyzing applications to characterize the requirementsfor sharing data between collaborating sites, examples ofdata structures that support collaboration, and guidelinesfor selecting appropriate synchronization andconcurrency control schemes.
