Hi Stuart, I'm glad you find pgfplots useful.
The origin for logarithmic axes is actually wrong - sorry for that. I have fixed it; it will be part of the next stable (watch out your TeX package repositories during the next weeks; the update is almost ready). Best regards and thanks for the report. Christian PS you got it completely right: the zerolevelstreamconstant thing is the correct approach. However, pgfplots uses it internally - and is simply sets the wrong value for log axes.
