Electronic commerce needs electronic meeting places to conduct business.
In this paper we discuss safety issues for participants and hosts. We then describe a system we are building, Safe Tcl, that will allow the construction of electronic meeting places with a range of safety properties. Safe Tcl has two attractive properties. Second, Tcl makes it easy to integrate the numerous facilities required in an electronic meeting place such as integrity verification and authentication. Tools for constructing safe meeting places for electronic commerce will become increasingly important as electronic commerce becomes more widely used.
