In this chapter, we introduce LACOME, the Large Collaborative Meeting Environment, which is a collaboration system that allows multiple users to simultaneously publish their computer desktops (workspace) and/or windows on a large shared display via a network connection. We discuss the design challenges of such systems for distributed environments. We conducted a series of focus groups to obtain feedback on the initial design of LACOME. Based on our findings, we developed high level design requirements for future iterations and made recommendations to improve the design of collaborative systems; these include the need for addressing privacy and security concerns when moving from a co-located setting to a mixed presence environment.
