This is a great idea for Anubis, funding future development and it being an alternative CDN.

Customers on the enterprise plan can either use Anubis's Managed CDN or host Anubis themselves via a enterprise license!

They can directly receive tech support from the creator of Anubis. (as long as they pay on the enterprise plan)

I don't see a problem with this and it can turn Anubis from "a piece of software" into a CDN.
