@bnfish can you check out how much work this would be?

@kknee from clustrmap's website:

Easy install: just paste a code we give you to your site and we will handle the rest.

looks easy enough!

Just checking in - Where are you on this feature?

@jbosch-noaa I'm not 100% sure that this was really wanted. @dpsnowden saw it somewhere and asked us to look into it, but a decision was never made to integrate it.

Ok. I thought so but wanted to close the loop here. Thanks.
