Thanks once again for the clarification! I suppose I should ask the more 
general question of whether the different L4Re mechanisms are documented in a 
manual or something of that nature. Although the reference documentation 
covers some of the concepts, along with APIs for use by applications, but not 
necessarily various framework-level abstractions (like Remote_app_model), it 
would be informative to be able to read something that discusses the 
techniques involved in building a system on top of Fiasco.

At the moment, I am just trying to persuade a program to run in a new task, 
which will hopefully only be a matter of properly initialising the details of 
the program environment. As well as paging in the appropriate segments of the 
binary in the right places, of course.

Paul
