speedlimit is a Leopard preference pane for limiting your network bandwidth to one of a couple different speeds—768k DSL, Edge, 3G, and Dialup.

It’s similar to services like TestFlight (they do more than just the wireless bit though – if you need a comprehensive solution, check them out too). BetaBuilder is free and the source is available.
