I've been experimenting with the way how to send the geometry generated in Grasshopper to external application such as Unity "as it is" so that one may control and view any kinds of parametric geometry on mobile devices such as iPhone. 

Here's the result.

Technically I'm using following technology in order to communicate between Grasshopper and Unity.

• Protocol Buffers (for serializing mesh object)
• node.js (for server)
• socket.io (for communication protocol)

This example is using a websocket so you could possibly control the geometry over the internet. I've also tried setting a node server on a raspberry pi to test and it worked just fine (a bit slow though).

This is just an example of communicating between Grasshopper and Unity but the same technique could be used for any kind of applications such as processing, openFrameworks, vvvv, max msp...etc.

I was wondering if this is useful for anybody else...
