Chullin 93: Sharing the Sciatic Nerve with Non-Jewish Neighbours

A new Mishna teaches us that a Jew may send a kosher animal to a non-Jew with the gid ha-nasheh, sciatic nerve, attached.  We do not need to worry that it will be resold to a Jew because the Jew would certainly notice the difference.  

The Gemara notes that it is important for the non-Jew to provide the Jew with the entire piece of meat.  IF the meat is cut up, it is disqualified.  The Gemara also suggests that geneivat data, stealing his mind/ fraud, is involved.  If we create the impression that the geneivat da'at is permitted,

Is this actual theft?  II Shmuel (15:6) provides a proof text: Avshalom "stole the hearts of the people of Israel.   The Ritva and others assert that we are not permitted to mislead anyone, Jew or non-Jew.

This daf alludes to] close friendship between Jews and non-Jews.  This is highly discouraged in other dap.  Clearly Jews have always been friendly with some non-Jews
