Wow that looks great! The URL has an extra "dot" before the SHTML though wh=
en you click on it.
Easy fix though. Are there no commercial applications for this kind of moni=
toring?
I see your graphs are powered by MRTG. =3D)

Shameless plug=2C I once developed a tool which was called multicast weathe=

Lastly=2C those guys at Poznan used to work on a tool called Muvi http://mu=
