Hi,

I'm not sure but maybe you could declare it in your org file as:

#+MACRO: BEAMERINSTITUTELONG My long and detailed Institute
#+MACRO: BEAMERINSTITUTESHORT Short Institute


And change the export code as follows:

\\institute[beamerinstituteshort]{{{{beamerinstitutelong}}}}\n

But I didn't tested it, it is just an idea that comes up reading your mail.
