Hi Chris, Sorry for the delay in responding to this- but it didn't make any difference: http://mapdata.thehumanjourney.net/index_26.html now includes the reproject option.
So, to make sure I understand- do I now need to use the spherical mercator option when overlaying on virtual earth, google et al even if all my data is served in EPSG 4326?

In 2.5, we turned the default 'reproject' option on WMS layers to 'false', because it offers a false sense of success in overlaying raster layers of different projections which isn't really accurate. Setting reproject: true should fix this issue for use now, but you should really at some point look into using SphericalMercator: http://crschmidt.net/~crschmidt/spherical_mercator.html explains some of the how.
