The pro version has filtering....

I'm not sure exactly what you're looking for. Do you really want a netstat type utility, or are you looking more for a network monitor? That is, do you want to see internal information, like what ports are open and what processes are using them, or do you want to see network information, like the actual data that's passing over the ports in real time. I don't think that a real time version of the former type is possible, as I'm pretty sure that polling has to be performed to get the data, and it's rather CPU-intensive.
