I've searched many times through the mailing lists, and I didn't found
a complete and rational discussion about the design issues of Mach/Hurd.
Perhaps could be a good idea to start such discussion now, probably
both l4-hurd and hurd will get benefit from this.

If you feel like this is not the right time for that, could you please
point me to that technical documentation? (That would be very helpful
for me :-)

Thanks!
