How do people deal with the need to Initiate workflows for anonymous users?

By default, SharePoint does not allow anonymous users to initiate workflows (either manually or from adding new list items).  In the past, I’ve had to start workflows either through impersonation (via code) or adding bogus credentials instead of using Anonymous.  For example, having a user registration site, whereby the completed registration would kick off a workflow to complete steps necessary for registering users.

I’m interested in how others with similar requirements have gotten around this issue.  Also, is this still an issue with SharePoint 2013?
