Yes, thanks, we will.
anyway I guess in nearest future high-performance network subsystem
(Stack, drivers) will be one of the our priority tasks.

We use own realization of communication of two L4Linux. We will
compare performance of nic_bridge and our realization.
Now our performance via 2 L4Linux around 184 Mb. Performance
PC->NIC->L4Linux is 94Mb. I think performance L4Linux->NIC->L4Linux
will the same.
