because it was (a) buggy and (b) trying to do too many things at once,
all of which html was a poor fit for.

you can generate a bare-bones python client with thrift; see
http://wiki.apache.org/cassandra/ThriftInterface

the Digg guys are working on a more idiomatic python client.

for 0.3 you can connect to the web interface on port 7002 (configurable).

In trunk we have removed the web interface in favor of JMX and
nodeprobe; see http://wiki.apache.org/cassandra/GettingStarted,
http://wiki.apache.org/cassandra/NodeProbe, and
http://wiki.apache.org/cassandra/MemtableThresholds
