Yes, currently the CIPE TAP driver has the capability to run on NT 4, 2K, and XP, but this first beta release of OpenVPN has only been tested on XP so far, because that's the only windows development machine I have access to right now. OpenVPN uses a slightly forked version of the CIPE TAP, but I'm in contact with Damion K. Wilson who is the author and maintainer of CIPE on Windows and he has expressed interest in decoupling and modularizing the TAP driver so that it can be used by other projects.
It would help if others came forward who have an interest in testing and maintaining OpenVPN on W2K and NT4 -- the binaries really need to be compiled on the version of windows that they are going to be run on, and compiling everything from source is not really an option for the end-user as it is a relatively complex undertaking compared with the ease of ./configure, apt-get, and emerge that we have come to expect on other OSes. While I expect that building OpenVPN for 2K and NT4 will be a relatively straightforward undertaking, the two areas where compatibility breaks down between the NT 4 series and the 2K/XP series are the .inf file (that's a file that tells Windows how to install a particular device driver and how it binds with other device drivers in the system), and the registry layout of network device driver info. OpenVPN needs to do some registry lookups in order to translate the TAP adapter name given in --dev-node into a real filename which can be passed to the Win32 open file function. I would agree with Bishop that as far as running on the 9x/Me series is concerned, I think it's unlikely given the much more limited networking driver model that is available on that series.
