Hmm.  I was thinking that the spplot() was the best-practices method for 
spatial data.

Is this a criticism of spplot() or the resultant png from the previous?

I've been working on a toGoogleEarth(spDf,zcol,title,filename) function

be working pretty well, and I'll see if he thinks its ready for sharing.
