Leads & Campaigns - help needed

I'm trying to figure out if there is any way to have a custom field display the number of leads associated with a particular campaign during a given month.
Random Campaign - Leads for Jan 08: 327
So far, master / detail relationships don't work (can't have it with leads), roll up summary because of the same reason, and I haven't been able to figure out a formula to calculate the value.
Does anyone have a work around to this? It seems that Salesforce is very limited when it comes to the roll-up summaries, or information pertaining to both campaigns and leads.
