code-rearrangement *in* lwIP ? lwIP is fully designed to work with 
NO_SYS = 1. Actually lwIP was first designed to work without an OS and 
was next reworked to run in its own thread using a simple callback 
through message box mechanism to keep it lightweight.

Again, lwIP contrib Git (and/or lwIP contrib releases) is more than 
complete with comprehensive NO_SYS=0 and NO_SYS=1 examples.
