stephen mallette commented on TINKERPOP-1839:
---------------------------------------------

> I am not quite seeing how one would access the ScriptEngine or its context.

I think that if you need this special level of integration which seems specific 
to JanusGraph you should create a {{Channelizer}} for JanusGraph that will 
allow you access to a number of core components of Gremlin Server (like the 
{{GremlinExecutor}}). 

> withRemote() gives access to a remote graph's traversal reference; is there a 
> similar story for getting access to a graph reference itself?

No - for "remoting" you only deal with a {{TraversalSource}}. There is nothing 
that binds to a {{Graph}} on the client side.

> We need a way to dynamically modify global bindings on the Gremlin Server.

>  along with the fact that most language client's interact with the Gremlin

> With JanusGraph's notion of dynamic graphs, there is no way to make use of 
> the `withRemote()` functionality or make use of language clients demanding 
> the traversal reference be bound to a variable.
> Therefore, we need a way to dynamically modify the global bindings on the 
> gremlin script engine without having to restart the server.
> Note; I answered the original stack overflow question above, however I am 
> pretty sure my answer is actually incorrect because the global binding will 
> be evaluated once at server start and the evaluated references will be stored 
> in the map and passed into the gremlin executor. Is this true?
