I agree with Jason. And I think it all depends on the architecture you are going after. Any problems why the job monitoring service couldn't execute the task in a different thread? Otherwise you could start a new process for each job that should be executed or call another service that would execute the job.

Also note that WCF cannot be use to do monitoring apps. WCF will only be triggered if a client calls it not by a specific interval.
