I'd use 3/4
(http://www.yoda.arachsys.com/csharp/faq/#one.application.instance). To
avoid large startup costs you can have your application EXE actually be a
shim that just does that approach. If it doesn't pick up another instance
running, it then proceeds to start the main application. This can work quite
nicely in conjunction with the Application Updater Block.
