#918 is to create a centralized, browser-based, management station,
(FWIW, I think this is The Way).

Earlier versions of Cassandra had an embedded web server on each node
that displayed a few properties, including a non-graphical
representation (a table) of the ring. We removed this webui because as
time wore on, more and more people came around to the idea that it was
better to put the time into JMX instrumentation and leave the job of
monitoring/management to applications and developers better suited to
that. Technically speaking, we removed it after this overall attitude
resulted in lots of excellent work being put into JMX, while the webui
suffered from chronic lack of maintenance.

A webui has a certain gee-whiz factor, but when running a real cluster
of any size, it's probably the least practical way to go about it IMO.
