If your purpose is so, use LANE.

If you can accept packet relaying for multicast case, where QoS-garanteed
multimedia application is needed most, there is no reason you can't
use packet relaying for the unicast case. So, don't try to have LIS for
end-to-end cell-by-cell relaying.

Rest of us will pursue more ambitious goal of the promised seamless
LAN-WAN connection.

I don't think we share the same idea on "the problem".
