trusted extensions for dfly, shouldn't be extremely hard to 
implement, we all ready break things down into messages,
inserting code to see if we have permission to execute the
message at the bottom layer.. i.e for disks the device message
well hell i guess that would be true for everything. 
 so I disagree that we need to port the trustedbsd code.
I believe it would be much easier and cleaner to do it ourselves.
