This is one thing that we had talked about many moons ago.  The postings were pretty much all agreeing that this would be such a difficult thing to do. 
Example, current owners in my area range from 35-45 and I know in the northern part of my state, they are 65-80.  BUT, they do all require the same information.
Perhaps a standardized description isn't such a bad idea.  I am not sure what department of NALTEA we could ask to help with this.  I don't see publications or events or membership doing it, not really ethics either.  Where would you classify this to be handled at?  Would it be a training tool?  For us to 'train our clients'? 
I know that the fee sheet I have for my company has different items broken down by price, such as current owners, 2 owners and current with e&r's, doc retrievals, update & record, deed reports and so on.  Perhaps one thing that would help is if you had your fee sheets broken down to price specific items and gave a description of what each was for your clients.  We revamped ours and sent it out with our E&O renewal info to our clients.

You know, just my 2¢ again.
