Hi Fabrizio and Derek,

  I'm also not fond of the idea of a separate executable as in any case
then we are at the mercy of people using the correct one from any given
installation of xrootd. It would be somewhat cleaner if people always
just used 'xrd', whereever they are, and _if_ the command was linked
with MonaLisa monitoring support it uses it. I guess there is then the
question of how it knows whether and where to send the information (if the 
support is linked). How would that have worked with the 'xrdmoncp' command?

  BTW, I'm still not sure what the _client_ side support for MonALISA
gives us that that the server side support would not (e.g. by reusing
the existing monitoring and simply allowing it to be redirected to
MonaLISA). Could you spell this out for me, Derek?
