The Build Brighton Hackspace (http://www.buildbrighton.com/blog/) has inherited an enormous laser printer, which is perfect for printing out little A5 double sided booklets such as my current document of choice: http://developer.coronalabs.com/demo/APIReference.pdf
There's a cracking mac app - https://www.macupdate.com/app/mac/21068/create-booklet which bundles pages into the right order for double sided output.
For some reason it just feels much easier to reference API calls from a little booklet, than plodding through a pdf.
Another exciting opportunity has arisen in the form of a London Lua user group meetup at the Marmalade SDK London HQ... This is a cracking opportunity to talk directly to the folks who build that SDK. http://www.meetup.com/London-Lua-User-Group/events/123416002/
