It would be great to be able to have Munchkin track web activity across domains. It turns out that one anonymous lead is abandoned and a new one is created when a lead moves from one domain to the next, even when they have the same munchkin code on them.
Here are two use cases:
Your company creates a mini-site that generates traffic to your main website, where they convert. Cross domain tracking would provide insight into how they interacted on the minisite.
Your company has a .com and a .net / .org domain with content on those domains.
