I searched a war-driving database for HSMM-MESH and imported the results here.  I just put the location and last date it was seen by somebody uploading to the database.  I'm sure it's nowhere near complete but it surprised me how many nodes were spotted.  I imported the data to google drive and shared the data set with maps.  You can view the results here: https://www.google.com/fusiontables/DataSource?docid=185e7xGGp3Nx94sbtrFmKrmdoE1hrmbC2tm9rgFY

I uploaded a picture from the map the link generates.
