There were articles (and mods) written for 1.6 but currently as it stands It wouldn't be super easy to do that. You could have multiple code bases that access the same DB (and a different URL associated with each code base), but you would have to do some hard coding of information which may prove difficult if you would like custom logo's for each one, etc.My understanding is that multiple branding support is currently planned for inclusion in future version 2.1. (We're on 188.8.131.52 currently). This sounds like what your looking to do. I will not speculate on the release date for it at this time though.
