How to Identify SPIDs Spawned by SSIS Package?

I've created a dynamic data transfer package using SSIS that programatically creates and executes a new package consisting of a series of data flow tasks. This package moves data between databases on a source and target server. The transfer package is executed from a simple application. I'd like to be able to show the package working on the target server in the app. How can I find which SPIDs to monitor, i.e. those SPIDs that have been spawned by my package and those SPIDs only? Is it even possible? Thanks, Iain
