and then ...

At one terminal.

  poeikcd start -f -n=ServerA -p=1111 -I=eg/lib:lib -M=MyP2P

And at another terminal.

  poeikcd start -f -n=ServerB -p=2222 -I=eg/lib:lib -M=MyP2P

At another terminal.

  poikc -p=1111 -D "MyP2P->spawn"
  poikc -p=2222 -D "MyP2P->spawn"

  poikc -p=1111 -D ServerA_alias server_connect ServerB 2222
        or  poikc -p=2222 -D ServerB_alias server_connect ServerA 1111

  poikc -p=1111 -D ServerA_alias go ServerB
  poikc -p=2222 -D ServerB_alias go ServerA
