A pre-emptive and sincere apology to a spate of recent commenter’s comments that were inadvertently relegated to a brimming heap of festering spam.

Please try again or contact me directly — some of you had questions, and I’m more than happy to help out with what I can and what I know. julian at nearfuturelaboratory dot com.
