If you don't mind running a process on your win32 boxen, maybe you could use PlRPC as part of a solution.

I don't know of any easier way to get at the live data, but you can use performance counter logs... If you set up a Counter Log, you can tell it to log to a text file, or any ODBC System DSN. Either of those can be easily accessible using samba tools or DBI. Anyway, HTH!
