"whilst many students are Web savvy and adroit in using software, they are largely ignorant of how to produce it. Perhaps then the real follow-on from Code/ Space is need for someone to write a book not on the geographies of code but a textbook to teach geographers to code."
Code/Space has been selling quite well apparently and the publisher MIT Press has decided to release the book as paperback version, which will be somewhat cheaper and will hopefully help it to reach a wider audience.

They have created a new website to disseminate their findings, at www.nuim.ie/progcity/ . Other details are pass code related publications and talks are still on my 'legacy' page.
