Examples include:
- Sponsoring an advertising campaign
- Sponsoring development
- Donating to the Darkcoin Foundation's address
- Consolidating the Masternode payments to one dedicated wallet without the need to start the hot wallet

Doesnt start-many do exactly that? Except I didn't get the hot wallet part...
I think crowning means 'donating' 100% of your MN payments to an address in your day to day wallet, so you can leave the MN wallet cold?
This will be very useful. I wonder if it will possible to "donate" one masternode payment to multiple addresses, say if you wanted to redirect one portion of the payment to your own day-to-day wallet and send another portion as a regular donation.
