Hello,

   I'm looking at the slave API here:

http://www.ros.org/wiki/ROS/Slave_API

  I have a couple easy questions.  First, in pubConnectionData there
is a "connected" field.  I am curious about what type that field is,
in terms of XMLRPC types.  Second, in requestTopic, if there were a
shared memory protocol, what is the recommended way to figure out
whether this potential subscriber is on the local machine? Would it be
to make a lookupNode() RPC call to the master and comparing the IP
addresses?

thanks,
-andrew
