I think I can answer this.

Behaviors do not require trusted ActiveX permissions. Even if you 
disable ActiveX in IE behaviors will work. You'll have to disable 
ActiveScripting (JScript/VBScript) to disable behaviors. You can also 
use a user style sheet to disable behaviors.

Behaviors are not the only solution but they have one important feature 
that is hard to achieve efficiently without using behaviors and that is 
that the element is can be initialized when it is started, ended or when 
the document is loaded. Normal Javascript is usually initiated when the 
page is loaded and this is too late for most real world scenarios. One 
can initialize the element earlier but that requires inline script 
elements or polling.

HTC stands for HTML components and this file ending was initially used 
for scriptlets. Scriptlets are a specific plugin type which is used with 
the object element in HTML.
