I haven't done any...

but looking at the fact that the data is not easily available from snmp, 
scripts to login and grab data from the routers may be the only way.

RANCID (shrubbery.net) has set of useful perl modules for logging into 
Cisco and running commands and capturing the output.

The NBAR data dump on the screen look like fixed column size and so should 
be easily parseable.

I had written some scripts similar to this for ATM bw monitoring when snmp 
support for atm  was non-existent.

Since the numbers here are data rates - you might want to feed it into 
rrd instead of Nagios directly.
