Project the google *data*? Google ain't yours, man: You can't do
anything fun with it (and definitely not reproject it!)

It is possible, using the trunk versio of OpenLayers, to convert from
Google coordinates to lon/lat. It is possible, using proj4js or perhaps
a custom transformation function, to convert from lon/lat to EPSG:27700.
I know of at least one person who has done it -- I'll try and remember
who and get him to post.
