I would say 2 is the best option. People have been splitting tasks
into multiple operations and combining the results on single machines
for ages -- MapReduce doesn't really offer any innovation there. The
innovation, and the buzz about it, is that it offers a reliable,
general-purpose, and large-scale distributed implementation of this
very basic idea. If you can accomplish that in this library, I think
there will be _a lot_ more interest.

I think a lot of the MapReduce buzz also has to do with the services
tied to it that further ease common scalability bottlenecks, the big
ones being Google File System and BigTable. It's really just part of
the bigger ecosystem.
