Best way to fix cracked front door glass?

[Roger Vi]

Tenant called to say neighborhood vandals cracked the front door glass. This is one of those expensive fancy glasses that you can't just patch up. Picture is below.

Does anyone know a good/inexpensive way to fix this? It is part of a double door and the other door has the same glass to match. I've been brainstorming and calling around all day I've come to the conclusion that the best long term fix is to buy a new door with no glass.
