I'd have to check, but I think we're sending a IQ Ping when the client misses it's first white space ping interval (whatever we deem is appropriate in that server config), and define the client to be disconnected when it doesn't respond in a timely manner. This covers both of your "the client is being silly" scenario's: to many whitespace pings aren't adding much overhead to the server, while to few pings are covered by the IQ Ping. I agree with you that it's all very unspecified, which could be improved on. I'm not seeing much of a direct _need_ to do that, but I'd not oppose it either.
