Wow, what you are suggesting here is definitely news to me. As far as I
understood it, SAI was the term they used for providing script nodes used to
drive node logic, and EAI was the name for the browser api. Perhaps I got
confused by the naming them. Do you have any pointers to documentation on
how this combination now called SAI works then?
You are saying that I write a script node and somehow have access to my
entire virtual machine, access to other script nodes running within the
virtual machine? i.e. lets say I want to have two nodes share a common
object, they can both access it?
Something like this is possible:
Node 1 -
...
public void initialize()
{
CommonObject o = Register.instance.GetCommonObject();
}
Node 2 -
...
public void initialize()
{
CommonObject o = Register.instance.GetCommonObject();
}
And all of the node instantiation and event listening capabitilties are
still there?
SuperNode 1
....
public void initialize()
{
Node node = EAILikeInterface.CreateVrmlFromURL(url);
node.getEventOut("foo").advise(this, "foo");
}
public void callback....

I didn't quite understand this, you have a link?
Thanks for the correction,
