Wave terms of service

An interesting item in the Google Wave terms of service came up this afternoon -

"Should you decide to charge users any type of fees in order to access to your Wave API Implementation, you must first get written consent from Google, and you may have to enter into a separate written agreement with Google before Google's grant
you permission to establish any such fee-based restricted access to your Wave API Implementation"

Thanks to Michael K for bringing this up.

I have to read this as including tuition.
