Obviously, that is ok in Texas.  The point of my post was to suggest examiniers in other states get the opinion of an attorney to determine if it would be concidered unauthorized practice of law in their state.
In Ohio it would most likely be unauthorized practice of law.  Crafting a disclaimer would not cover the examiner here from being seen as practicing law.  It varies by state.  When we are approached by investors, we refer them to one of the title agencies we do work for to get a commitment or letter report.  We still get the work, the investor knows we are doing it for them, but working through a title agency makes it legal in Ohio. 
Regarding the work for national companies, I was curious about that when they first showed up several years ago.  Several attornies told me there would be no problem as long as the purpose of my work was for the preparation of a title policy or guarantee.
