As for the 1 Question(if i understood Anet correct^^), you have to use the Anet entity pointer(cause they are the same on all connected machines).
use
enet_ent_globpointer(you);
to get a var holding the global Anet entity pointer.
Send it and when received do
you = enet_ent_locpointer(globalpointer);
edit: globalpointer is the var you received(in this example, you can use any other var instead)
Should work
