Icon for iOS app

Looking for some critique on this.

We're getting ready to launch a new app, a browser with built-in advanced link sharing functionality to promote ideas. I could tell you more, but I'd have to kill you afterwards. ;)

The globe represents the www, and the ring of dots and lines represents people sharing.

I've found it difficult to think of something to get across the idea of sharing, as it doesn't really have a physical counterpart?

There are not one but two widely recognised sharing icons out there, but their licence states they cannot be used as part of an icon.

Any thoughts, feedback or ideas? Thanks guys.
