Rhino4.Inteface in Rhino Common

I am currently working on an update to a series of excel to GH components, moving them to Rhino Common using the latest VB nodes. While a huge fan, Im still new to Rhino Common and familiarizing myself with the way its structured.

In an earlier implementation I was using the method outlined by Damien Alomar, see:

http://www.liquidtectonics.com/2009/01/grasshopper-excel-part-2.html

However, this used:

Dim rh, rhScript As Object

rh = CreateObject("Rhino4.Interface")

rhScript = rh.GetScriptObject

The end goal being to create a hidden point which triggers a rhino update using:

Call rhScript.Command("_-SelNone _-Point 0,0,0 Enter _SelLast")
refObj = rhScript.SelectedObjects()(0)
str = """" & CStr(refObj) & """"
rhScript.command("_Hide ")

The Object GUID was then passed into a macro in excel which would move the point anytime excel updated.

The issue I've run into in starting this is finding the equivalent to CreateObject("Rhino4.Interface"), in Rhino common.

I would greatly appreciate any help on how to establish access to Rhino using a similar method, or any other suggestions on methods to allow an event in an outside application to trigger an refresh of a component.
