VO service monitoring

[Rob Seaman]

Howdy,

Has anybody considered how best to add our VOEvent brokers to this list:

	http://heasarc.gsfc.nasa.gov/vo/monitor

This seems like an excellent way to raise VOEvent's visibility and to  
enforce some discipline on maintaining our services.  Vanilla TCP's  
"i am alive" packets are pretty much designed to support such  
monitoring already - seems like this should be an easy goal to meet.   
Would just need a client that speaks vTCP on one side and whatever  
the monitor wants on the other.
