Okay, well I'm a bit biased, spending a large part of my life surrounded by Open Source Software, newish technology and new ways of delivering services, but you have no idea what a nice feeling it was to see a note from Eoin Hennigan in my email box this morning (Thunderbird email client incidentally). Following that email to his site what gave me a real sense of pleasure was to see that you can get Eoin's book as a free download OR you can order a copy via Lulu.
Now we buy a lot of technical publications, and other specialist books via lulu - in fact there could very well be something up there soonish with our own names on it (technical so not of interest to anyone here), but to use this delivery mechanism for a crime fiction book - well it'll be fabulous to watch how that goes.
