[edit] Microsoft Windows
[edit] Status
It is not known of any planned port of DTrace to the Windows operating system. (Yes, I'd love to DTrace Windows too).
It may be possible to DTrace the operation of an emulator, such as Wine, and as such see the operation of a program. This would not be able to troubleshoot all issues, such as certain interactions with the operating system.

[edit] FreeBSD
[edit] Status
Most of the initial porting-work was already done 2006, but licensing issues prevented the integration into the source-tree of the FreeBSD-project. After working around this problem by putting everything into a seperate module, so no parts of the kernel-source have to contain CDDL-licensed code (just like ZFS on FreeBSD), the porting was finished. DTrace is now part of FreeBSD-CURRENT (development branch, 8.x) and it's planned to merge the code into 6.x and 7.x as well.
