[erlang-questions] single packet authorization in erlang?

I'm working on an application that uses Single Packet Authorization (SPA)
to protect access to our servers. We currently use fwknop client/daemon,
but it's fairly heavyweight (and slow) for our purposes. I was wondering if
anyone else is playing with this at all?

At the least, I'd like to be able to create and send the SPA packet without
using the fwknop library/client. It seems like it should be straighforward,
except that I haven't found a decent description of what the packet needs
to look like. It also seems like implementing the server side should be 
perhaps using michael santos' pcap modules.

Any pointers or guidance would be appreciated.
