Would'n it be better to tune the routstr code not to behave so that it can't be differentiated from dozens of ddos attack patterns?

It's a great ecash usecase and I believe it can be easily fixed to prevent:

- hitting frequently mint rate limits on read/write mint APIs
- ddosing specifically the mint database through long time ws subscriptions to circumvalent rate limits
- creating thousands of invoices that get never paid

If you need I offer my assistance.
