Yes, never tried with more, but two instances are working fine.

The l4shmnet negotiates client and server automatically.

l4shmnet needs some namespace to find the other side:

- local my_channel = l:new_channel();
+ local test_l4shm = l:create_namespace({test_l4shm = "shmns_1"});

-    myL4shm = my_channel:svr(),
+    test_l4shm = test_l4shm:mode("rw");

Do not forget to enable CONFIG_L4_NET_L4SHM
