For debugging and testing (32bit vs 64bit and also version/build number vs version) and in a couple of instances for customers with >1 installation of FME Desktop, it would have been handy to allow the WorkspaceRunner to allow you to determine which FME the sub process should run in rather the one defined by the path environment variable. An option to select or detect which FME to run would be useful.
In the past I have solved this by effectively building a Custom WorkspaceRunner by using a SystemCaller to do the job instead.
