I don't know what you mean by domainkey in this example, but assuming 
you meant that you'd like to implement somerthing like a new RR for  
*.domain, again I ask: to what end?  To protect non-existent domains?  
The only case covered is the analogous wildcard MX, and in this case 
adding a TXT tag doesn't actually solve the problem.
