Bandwidth Monitor?

[BM]

Does anyone know of an app that will monitor the bandwidth usage of a specific port or application.

Basically I would like to monitor my usnet usage. Either monitoring the port or client exe. Ideally it would give my an alert if I am coming close to my cap and then block the port if I reached it.

Any ideas?

netlimiter shows how much bandwidth a particular program (exe) is/has used, no alert or auto capping though...

netlimiter certainly does the job and you can put a cap on a given port or app, doesn't alert though I don't think.
