Other browsers like IE, Chrome does support this feature.
Launch the first instance without -no-remote then Windows will use that instance for links from other applications and you should be able to openurl for that instance. There is not any platform where opening urls into an -no-remote instance is supported. Furthermore there are plans to disable DDE when switching to VC2010 is complete Bug 491947 Bug 513742.
Hi Kevin, The issue here is that: I would like to have multiple instances (using different profiles "-no-remote" option) concurrently, and be be able to do a ShellLaunch or DDE and select the instance where the second tab/url should get launched. For example, the following works in Chrome: Chrome.exe --user-data-dir=<dir> "URL"
