I am using the Connection Manager Administration Kit (CMAK) to create vpn connections for my users, if it is possible how do I create a custom action that launches an executable that runs synchronously?

In the help file it says

Only DLLs run synchronously, meaning that Connection Manager starts the action and then waits for the function to return before continuing

Is there any way around this?

I have seen something similar called VPN-Q which from the screen shots appear to do just that.
