Giving Calendar Access to non-members

We have a scout troop that serves many non-members. We'd like to keep our calendar in lds.org so we don't create conflicts with other ward activities. However, there doesn't seem to be anyway to share an lds.org calendar with a non-member.

I guess I could periodically export an iCal and then import into a shareable calendar but it is kind of awkward and was hoping for a better solution

That same question was asked in the thread Troop Calendar visible by non-member parents.
