Services for Unix is a tool that is generally thought of as a migration tool. This new version comes with a fully compliant POSIX subsystem that runs on NT, NT 2000 AND XP. This vesion of Unix is called Interix and includes both the C and Korn shell along with inproved Network File System services. It is priced at $99.
Microsoft has also ported .NET to FreeBSD. Does this growing acceptance of variants mean a kinder gentler strategy to co-exist with Unix or is a Fox in the Hen House kind of thing.
