I saw this done in the Slabodka Yeshiva in Bnai Brak: only your first
name is used. I'd imagine that in case of ambiguity, they may point -
but this is an issue even with the "ben" system. :-)

Apparently, when calling up the Roshei Yeshiva, they say YaAmod and
point, not wanting to call the RY by name, but I never saw this
actually happen.
