So, we're don't attend to develop ikernel for the MMUless systems, it's a not a 
good way,
it's more research than tribble development ;)
FS is ready for the 70 percents, it's a not bad I think, and I've planned to 
finish this for the one week or two weeks max with testing.

So, now development has a two frontage, first is the lowlevel development, the 
second is the development in the userspace with wrappers to easy porting to the 
native Jari kernel.
I think that this is a good way.

Servers API partially designed, see (ikernel/include/ipc/port.h) we're just 
need ports and JP stack (that already ready)

I think that we're must be targeted to the lowlevel now (my subpart needs for 
it at this moment heavly) and for connecting up our two parts.
