Ah yeah.  I looked at densitymap and I think that is the way I am going to go, inserting the javascript with the ushahidi_action.header_scripts, it appears that plugins get called after core JS so I can overwrite anything I want in core.

This makes a lot of sense and I have to say I am a bit surprised that the core dev team did not take this approach from the begining since ushahidi is so map and by relationship openlayers centric.  OpenLayers is an amazing library that has a ton of features of which ushahidi core uses a small subset of.  Making it easier for plugin developers to hook into the mapping interface and leverage the power of OpenLayers whiloe maintaining the MVC architecture that the rest of the system would be fantastic.

Thanks!
