Hi Frank.

>Would the Stonefield product be of use in this situation?

Yes, SDT can help with this. One way it can help is in updating structures after your users have made multiple copies. Say you add a new field to one of the tables. You need to add that new field to every copy the user has made. SDT's Update method can make this easy.

>How much would it cost and would licensing be required for utilization of the product for our customers?

SDT is $299 US and is royalty-free.
