I am aware of the various security-related tools that were available prior to the NeoPwn beta, but I am wondering if any of the newly ported tools by NeoPwn could be used on the N900 without installing the NeoPwn kernel.

These tools should already be in ARM (v7) format, I am especially interested in tools like NetDiscover (http://nixgeneration.com/~jaime/netdiscover/). NetDiscover is listed on the NeoPwn software list:
