I worked on Pants at Foursquare for a while and when coming up to speed on Spark was interested in the possibility of building it with Pants, particularly because allowing developers to share/reuse each others' compilation artifacts seems like it would be a boon to productivity; that was/is Pants' "killer feature" for Foursquare, as mentioned on the pants-devel thread.
Given the monumental nature of the task of making Spark build with Pants, most of my enthusiasm was deflected to SPARK-1517 <https://issues.apache.org/jira/browse/SPARK-1517>, which deals with publishing nightly builds (or better, exposing all assembly JARs built by Jenkins?) that people could use rather than having to assemble their own. Anyway, it's an intriguing idea, Nicholas, I'm glad you are pursuing it!
