Good catch. We should note the probing issue in the Security and 
privacy considerations section. This was not touched upon by PING, 
likely since the spec does not mention DIAL explicitly. We could also 
consider amending the respective algorithms with a note. E.g. in 
[Monitor the list of available presentation displays][1]:

>The mechanism used to monitor presentation displays availability and 
determine the compatibility of a presentation display with a given URL
 is left to the user agent.

This could be amended with text that makes it clear that the given URL
 may reveal information about the user's system, e.g. apps installed 
to handle the specifically crafted URL. Also note the UAs may 
implement measures to mitigate that and how. If this warrants changes 
to the algorithm, we should look at that too.
