...so i looked at PEAK's getnodeid48() routine and borrowed the Win32 calls from there, with a comment giving attribution to PEAK. There appears to be a transcription error, there; the second win32 import isn't covered by a try/except and the ImportError seems to have disappeared as well. Also, for Python 2.5, these imports could probably be replaced with a ctypes call, though I'm not experienced enough w/ctypes to figure out what the call should be. Similarly, for the uuidgen module, you've not included the C source for that module or the setup.py incantations to build it. But again, it could probably be replaced by ctypes calls to uuidgen(2) on BSD-ish platforms. I'll take a whack at addressing these once the code is in, though, unless there's a ctypes guru or two available...?

I don't know if this is the uuidgen you're talking about, but on linux there is libuuid:

from ctypes import * lib = CDLL("libuuid.so.1") uuid = createstringbuffer(16) lib.uuidgenerate(byref(uuid)) 2131088494 from binascii import hexlify hexlify(buffer(uuid)) '0c77b6d7e5f940b18e29a749057f6ed4'
