Redmine

I'm using redmine to consolidate a couple dozen different bits of open source software that I've written over the years into one coherent place, and so far, I'm loving everything. As each of these project individually are going to be really low activity, I was hoping it would be simple to integrate a composite activity view into the main page (just the sum of the activity pages on all projects).

Any pointers as to where to dig in to try to do that? Is there enough exposed via the plugin API to do this with a plugin? Any help, suggestions would be appreciated.
