I have noticed a great deal of lovely heraldry in Neufreistadt since I joined, and it seems to me a good idea to have in the CDS, just like in many real-world nations, an official body to register coats of arms in the CDS, so that it can be said that a particular coat of arms is the official coat of arms of a person or institution.
Perhaps we could have an official Register of Heralds (perhaps overseen by the Guild, with a Registrar of Heralds appointed by the Guildmeister) to register which coat of arms may be used by which body or individual. The Chancellor, the Guildmeister and the RA could have the power to grant a coat of arms to a person or body, either, in the case of an individual, as a recognition of outstanding service to the CDS, or, in the case of a body, that it is an important institution that deserves some degree of symbolic official representation, which would then be designed by the Registrar (with input as to the design from the grantee), and registered against that person or body's name in the Registry of Heralds.
Either the position of Registrar of Heralds should be paid a standard salary, or, alternatively, be allowed to charge a fee (which the granting body will decide whether to pay itself, or let the grantee pay) for each coat of arms designed. There should also be provision for registering existing coats of arms, or those designed by outside bodies.
Then, any person or body in the CDS using an unregistered coat of arms, or a coat of arms registered to someone else, could be subject to a fine.
The above system, incidentally, is based on the real-life law of heraldry, which is undoubtedly the oldest form of intellectual property law in the world.
The trick is, however, finding somebody willing to be the Registrar of Heralds...
