Remotely terminate a Sharepoint workflow

Has anyone had experience 开发者_StackOverflowcanceling a workflow via webservices? Is it possible?

If you write the web service yourself, it can do anything you want.

Here is a code example for cancelling workflow: http://social.msdn.microsoft.com/Forums/en-US/sharepointworkflow/thread/e5fc79f8-ca3a-421a-ab8a-78fcb3365b46

Edit

There is a workflow.asmx, but it looks like it has a startworkflow but not a stop
