Subject Re: admin web UI

Hi! I was working on a separate monitoring client, and not a per-node approach.

At the time, we talked on having a single server that queries the
nodes on a Cassandra cluster.

There's some discussions on the list, about technologies being used,
etc. I was pretty busy these last weeks (and some days out of town),
I'm actually working on a python based UI on the server side, and got
some time for testing pylons and tornado for two different approaches,
one with synchronous and one with asynchronous requests.

Also, someone just told me of another JMX/Rest interface, different
from the one I was going to use (and adapt).

You can find an architecture draft here:

At first time Django was proposed (just for being the most
well-known), but it's oversized, and later we decided to go with
Pylons.
