Filtering by tags in Neatline

I would like to be able to filter records on my Neatline map based on tag.

I found this thread from about a year ago:

http://omeka.org/forums-legacy/topic/neatline-using-tags-to-toggle-map-data

which basically describes and offers some leads on how to do this, but my programming skills are not at the level where I would actually know how to implement it.

Has anyone attempted something like this/know where I might start in attempting it myself?

Thanks.
