We have something similar to what you both describe -- in our case a large-ish name index that cross-references names of people to the various collections in which they appear. I agree trying to cram it into EAD doesn't make much sense -- however, if your goal is to XML encode that information, the ISAAR standard (for describing corporate bodies and people) will soon have an associated XML schema (I believe it's being called EAC-CPF; the beta was released in 2004, see http://xml.coverpages.org/ni2004-08-24-a.html) and that might work. I'm pondering the use of it for our name index. Both ISAAR and EAC-CPF provides for specifying "related resources" such as collections, archives, etc. which one could use to connect the record for a person to the various EAD records for collections in which they appear. (This is all *very* tentative -- i.e. mostly in my head so far -- but I think it has possibilities...)
Of course, much depends on how much time/effort/money you want to expend on XML encoding the information...if you're interested keep an eye out for when the EAC schema is officially released...

We have a different situation, however, with a card index that indexes
persons and topics across a number of record groups of University records
up to 1850. Is this latter scenario the one you are asking about? I have
not attempted to encode this. The cards are handwritten and thus do not
lend themselves easily to low-cost transcription, although I would very
much like to have them transcribed. I suspect I would either not use EAD
or use some very unorthodox EAD encoding for this data.
