I will answer for me and, hopefully, Erick and others will also answer. I do maps for individuals with health problems. I cannot ask each of them to download the software just to read a personal map -- even if the function of the viewer works perfectly. I can post generic maps, and I hope my disclaimer is adequate that the maps are only generic and educational, not prescriptive. But I may only have a one-time linked map for them to do their own follow-ups.
I can imagine that anyone who does research for personal reasons as a consultant -- health, financial, legal, or even very unique such as a specialized field of interest -- would not post on Connect or ask a client/customer to add downloading any (even wonderful) software to the consultation results.
For the public maps, I was able to create a website and the images on the site (jpeg versions) link back to the posted linked maps on Connect.
Erick, I am curious about your need, if you would care to share it.
Kathy
