It would be great if we could upload an Armory watching-only wallet and then tip addresses would be pulled from that pool of addresses.
In this case, instead of relying on the Blockchain.com API, where the service is known to go down from time to time, is to instead have the plugin author include the ability to upload an Armory watch-only wallet and then draw from that pool of public keys each time a post needs a new bitcoin address.
This would remove the centralized point of failure, increase the privacy of the tip sender and receiver because the information would not be going through Blockchain's server, decrease miner fees and retain the same level of security because the Armory wallet could be stored by the tip receiver in offline cold storage.
