Ah, looks like this is the library Subbu Allamaraju refers to at http://www.subbu.org/blog/2011/11/apis-are-a-pain--the aim of ql.io is to alleviate the challenges of "aggregation, parallelization, and orchestration of forks and joins." (i.e. in practice, "consistent RESTful APIs don’t matter as much as we think," nice though they may be.)
