The functionality of OAI could become part of SRW. It needs some extra recordSchemas and the ability to search deleted records. The big advantage of providing extra search facilities is that one is able to build an archive based on other attributes than only a timespan (as is the case now in OAI).
We just started using OAI for getting records that we will make available with SRU.

Exactly! I think it is a great mix. As it happens, the database I am
providing SRW/SRU access to is also our OAI database.

So you see SRW as a query mechanism against the aggregated database,
not an alternative to OAI to form the aggregated database? (That is
what I was thinking of too.)
So use OAI for data aggregation, and SRW for distributed searching.
An implementation can choose how to mix the two protocols to build
an overall system.
