mobileread has a subversion+trac setup at https://dev.mobileread.com/trac/hub/
that looks like it would be a good place for DR projects. There is also a mobileread mediawiki that I think could become a better resource than searching through forum threads for pointers and info. I did a little editing to http://wiki.mobileread.com/wiki/DR800SG
but for example a page documenting what each of the open source OS components is responsible for, how to correctly add a gconf schema without clobbering another plugin's additions, etc would be very useful.
For those that just want to browse the iRex released sources you're welcome to use my personal repository at https://beast.cis.upenn.edu:8888/tra...ex-source/tags
