Are you asking if it works over NFS or are you asking if it works on windows?

From the manual:
"flock() will not work on NFS and many other networked file systems.".
"Index size is limited by 2GB for 32-bit platforms."

Developing with lucene on your local machine (running xp) should be no problem as long as you're not running 32bit win and have indexes over 2gb or are using a networked FS.
