This doesn't sound like too bad a job, but it's not worth it unless
people are willing to use and support it in their code.  Obviously, a
streaming XPath subset is appropriate for use with streaming parser
APIs like SAX and STAX -- where else would it be useful?  XML
networking?  Search and indexing?

There's also the question of context -- would the only context be the
stack, or do people hope to have access to left siblings as well?

All the best,
