Hey,
OSM is nice if you want to display a map on a website. There's already a html code to integrate the map inside the website...
And there's a nice plugin to add .gpx file displayed on the map (gps track), inside the website (wordpress plugin)

So, it can be nice to have something useful with B2E, a plugin or natively ?!
Displaying a .gpx can be really cool feature too!!

Some things here:

Many thx to contributors and devs ;)
