Is it possible to call a process model start point from outside of Appian? I wo

We have a few processes that are started by webservice calls and another one that receives a JMS message using the 'receive message' event trigger. Both generally seem to work well. The JMS works flawlessly I think, but the webservice call might be an issue if the calling process is expecting a result/response quickly. One of our developers is attempting to create a tempo user task/form and pass back the task id to the calling webservice (so that a URL link directly to the form can be presented). She is having some issues with timing, i.e. it needs to be quick or the calling webservice may time out.
