I'd never heard of L4Ka before (only just googled it). I am not sure 
what advantage this is supposed to have over other microkernel based 
hypervisors such as Xen and ESX.

I remain skeptical on that considering that the overheads on microkernel 
based hypervisors (Xen, ESX) are 21%+ on full fat x86 iron.

Seriously, though - what's wrong with doing away with virtualization and 
just using isolation instead, like on Vserver? I don't see the gain from 
using a hypervisor. What would that enable, and how likely is that to 
end up being used in a plausibly realistic scenario before this decade 
is up?
