Hello,
I have written up the first of a series of articles about using seL4 as base platform for the Genode OS framework:
http://genode.org/documentation/articles/sel4_part_1
I hope that it contains useful bits of information for novices of seL4 and Genode alike. Even though the article outlines a few hurdles, the overall experience of using the kernel had been overly positive so far.
For those of you interested in tracking the progress of the ongoing work, here is the corresponding topic branch:

Cheers Norman
