Although I do have enough of NSP and NICE to allow SH KNOWN CIRCUIT and SH ADJACENT NODES. I don't have any real NSP at all yet, so in that part you're clearly way ahead.

On the other hand, Python makes a lot of what needs to be done a great deal easier than it is in C, especially once I put some infrastructure together. Packet parsing is an example. paul
