"Previously, we have presented one of the two opensource licensed projects related to creating a C# kernel. Now it's the time to complete the set by rightfully presenting SharpOS, an effort to build a GPL version 3 + runtime exception licensed system, around a C# kernel of their own design. It is my pleasure and priviledge to host a set of questions and answers from four active developers of SharpOS, that is William Lahti, Bruce Markham, Mircea - Cristian Racasan and Sander van Rossen in order to get some insight into what they are doing with SharpOS, their goals, their different design and inspiration."

What exactly is useless about those two points?
Memory is completely isolated from process to process, and communication is done via secured channels.
Optional hardware isolation for untrusted (or even legacy and VM'ed native code) processes, and the ability to proof code before it's ever run.
The advantages are all about making these assumptions, and taking the stress off of the developer to do this tedious work.
This is basically software memory protection and instant IPC without using the processor at all.
This does two things:
It frees you of the speed penalty of many context switches (so you don't have to do something dangerous like implement shared memory), and it makes your code heavily portable.
Since you're using no features from the Intel architecture you would easily be able to port it to another platform.
Now when you look at Channels for IPC it seems like a bad idea, until you factor in that it's an instant transfer of data.. and a secure one at that.
The concepts start to look a hell of a lot more attractive given the details.
