Why does cfide need to be in webroot when using form tag bind on apache with virtual hosts?

All;

First, if this thread is ignorant let me excuse myself.  I haven't really programmed in Cold Fusion since the DBML days and it was a CGI interpretter running under O'Reilly webserver.  I have been busy in the Java and PHP world.

But I digress, I have returned and I am extremely excited about the features and easy of use in Cold Fusion.  I can do a lot more, a lot faster, with a lot less code = more money and more time.

But,  I just spent almost 3 sleepless days figuring this out and I was wondering if someone could help educate me on this one.  Apologies in advance if this is well documented in the Cold Fusion docs, but I don't read docs, I dive in head first, and usually break my neck.

I am using interdependent <cfselects> with the bind feature to cfcs to populate them.  I have based it on the <cfselect> tutorial, example 2. 

For reference it is here: http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-7afe.html

or in your local /cfdocs/

I am using CF under Apache with virtual hosts.  CF 9.  All setup as a dev machine. 

For some reason the <cfselect> binding example 2 worked fine in my apache web root. 

But every time I tried to use the example under a virtual host the test page would find the bindFCNS.cfc but the html <selects> in the output would not populate.  No errors, just no data. 

Copying the /CFIDE/ to the virtual hosts web root solved the problem.  This did not seem like the inductive reason at the time, which is why I spent 3 days thinking it might be the way I was implementing Request Handlers in the Application.cfc or how I was handling OnError as well as other errata and other programming customizations.

So, last ditch I just copied the /CFIDE/ to my virtual webroot on two different apache test/dev virtual hosts/domains and these <cfselect> bind examples are working.

My question is WHY?  Because honestly this seems extremely arbitrary and when I go to production I really don't want to have to deploy the CFIDE in my webroots for each installation of these application.

So, why?

Is there another solution?

How are people managing this?

Thanks
