Sharing JEvents data between two sites

[jckinsey]

I have 2 sites, one is a church, the other is the dayschool for the church. The dayschool is a subdomain of the church site, but they have separate databases. Is there any way to share the data from one JEvents site with another? I really want to make this easy for the staff to manage, and since the church needs all of the info on the dayschool site for scheduling purposes, I don't want them to have to enter it twice. We also want the dayschool to have access to the church data.
The only othrr alternative I can think of is to hyperlink the church calendar as a menu item on the dayschool site, but I would love to have it more seamless than that.
Any ideas?

Thanks,
Jeanine
