Yes. Everything doing lookups in .tel. For example try getting the  
naptr records for telnic.tel. Responses of 1500 bytes or more are not  

There is also a depressing tendency for bloat. New applications and  
services generally want to store and retrieve more data than existing  
ones. So imagine if CERT records take off. Or what DNS data could be  
associated with an RFID tag or smart card.
