Fingerprinting remote OS : Python

Question

I am trying to write a Python script that when given an IP address it will attempt to identify the OS of a remote host. I am aware Nmap will do this easily but I would like to try and write one in Python.

Having the ability to identify Linux/Windows/Mac etc would be great but would prefer to identify kernel version.

Any suggestions or directions that I may be able to investigate?

Scapy and p0f are your best bet. People have had differing results however.
