In light of the details found in answers to this question, which suggest that neither Chassidish nor glatt nor non-glatt Ashkenazi meat is halachically acceptable for Sefardim, would there be any leniency for a Sefardi to eat meat in the home of an Ashkenazi? Presumably, the Ashkenazi would not be serving Beit Yosef meat, since--according to details in the first link above--that meat would not be kosher for the Ashkenazi himself (at least if he held to the glatt standard, and possibly also if he did not).*

Are there any kashrus standards for meat that would certainly be acceptable to both Ashkenazim and Sefardim in the stricter (i.e., ~glatt-eating) groups?

* According to HaRav Braun of the Beis Din of Crown Heights, New York, Ashkenazim who hold by the glatt standard may eat Beit Yosef meat, but I have seen other sources in addition to the ones linked who say the opposite. CYLOR if it applies to you?
