Thursby software has released MacNFS, it's new Mac-based version of Sun's Network File System (NFS).
Designed for the Mac it offers several functions - including sharing files with other Mac users and 'multiple vendored' UNIX machines.
MacNFS is uni-directional - a Mac can see the UNIX machines on a network, but the UNIX machines cannot see the Macintosh. UNIX machines can be accessed on the network by opening the Chooser, picking MacNFS and selecting from the UNIX machines on the network.
The company also sells Dave, which lets Macs access a Microsoft network. Dave is bi-directional - Macs and Microsoft machines can see each other through it.
The company has a demo of MacNFS available as a download from its Web site. The full program costs $149.
