Mer now has an instance of IMG running. (Docs at http://autodoc.meego.com/mint/imager/ )
It offers two capabilities: 1) A web interface for user driven image generation, on demand, that can be easily acessed by multiple team members 2) BOSS driven automated image generation for QA purposes. This is not an open public service (because we just don't have the resource to provide that) and is primarily intended for automated use by Mer QA. However, if users of projects like Nemo, PA or any others want to try it out, please discuss your interest in #mer David -- "Don't worry, you'll be fine; I saw it work in a cartoon once..."
