Yes you can. Also, there's a xapian database in my home directory (~enrico/anapop/something IIRC) on people.debian.org that is built with the popcon data, and you can query that database to quickly get a count of "submissions having package X AND NOT package Y" and "package X AND package Y". That Xapian index indexes popcon submissions as if they were "documents", and installed packages as if they were "terms". The database is updated using a weekly cronjob that rescans the whole popcon database. I've quickly tried in the past[1] to come out with ways to hook the indexing process into popcon so that I could do realitime indexing of the data (it gives an up to date index and doesn't suck 100% cpu on gluck once a week), but I got the impression that it required having more discussion than I was motivated to have at the time. If more people are interested in using that xapian index, it can make sense to rehash this.
