[Plugin: All-in-One Event Calendar] Is there a way to load the Upcoming Events Widget on OTHER WP si

Our site (familyeguide.com) is a resource for family activities in our area. We’ve had several requests from local churches and businesses to include some form of our calendar on THEIR site. Is there a way to load the Upcoming Events Widget on their WP site? Or is there something similar for external sites? Thanks!
