OX X vs BSD
• Open source UNIX® foundation
• POSIX compliant, Open Brand UNIX 03 Registered Product
• Open source kernel based on FreeBSD and Mach 3.0
• The man pages are for BSD
In my opinion it is giant leap backward. I have used Unix and Linux and find both have better, more productive, user interface than OS X Leopard.
Is there a way to strip off the OS X shell and run the BSD Directly?
Will the MAC applications run on BSD?
Will BSD applications run on OD X?

The operating system core is open source, you are free to take Open Darwin and do whatever you want with it. Want to build a new OS on top of it? Sure, you can.
What Apple did was a calculated move: they figured out that if they didn't have to build a whole OS from scratch, they could channel all of their resources into the user experience. While Microsoft was struggling horribly trying to get their OS to run without freeze, Apple moved out of OS 9 on top of a rock solid Unix foundation.
The funny thing about OS X's underpinnings is that you can pretty much run any Unix application in it. Even better, right around 10.2, people went crazy and started making sure all popular open source *nix applications would be represented in the OS camp. This is why when you got almost all major *nix application project websites, right out in front you will see that you can get it to work on OS X.
Is it perfect? No, especially when the projects are still running on X11 which is a pain. But you have to acknowledge that you can take a brand new Mac, boot it up and pack it to the hilt with a lot of the awesome stuff that you would expect from installing a Linux distro.

Mac applications, which require the OS X windowing environment, API's etc, will certainly not run on Open Darwin or BSD.
It should be pretty straightforward to port any BSD/Unix/Linux application to Open Darwin, but I wouldn't expect them to work "out of the box". A number of projects (MacPorts, GNU-Darwin, Darwine, etc) have been porting popular applications to Darwin, so there should be a fair amount of stuff out there that works.
