gpuds framework: planning stages

Lately I've been thinking about taking my personal photo sharing website and creating a open-source framework version of it.  Why would I bother wasting time on this when sites like Flickr, Snapfish and Photobucket exist?  I feel as if they are still lacking many features that photo sites should include, like original high-resolution file downloads and group file uploading into the same album.  To me it only makes sense.  Say you're at a family reunion and everyone is taking pictures.  What sense does it make for everyone to have their own photo albums on different sites, with pictures of the same thing?

Additionally, I've had a couple people ask me if they can have their own version of gpuds to put on a site for themselves.  I've spent a decent amount of time lately looking at open-source blogging software like Mango Blog and BlogCFC, I thought I'd take a shot at developing something myself for photo sharing since I already have done a lot of the work in the form of gpuds.
