The reason I would like to have this included in notmuch is because I use it for an Android client (http://www.nexoid.at/tmp/search.png). It is written in Kawa Scheme, and works on all Android devices I have access to :) Only reading for now, composition later. After some cleanup I'll make it available to anyone interested. S-Expressions are much easier to use than json here.
Greetings, Peter
