Web viewers

[potlicker @ morebbs . com]

Suppose there is a firewall with a hole poked in it that permits access
to a web server.  Suppose also that the people posting on the web server
are placing documents there in native format and providing viewer applications
for people to look at the documents, so that they don't have to churn out
lots of html documents.

What are the risks to the web site from providing viewers such as 
Quick View Plus and Key View instead of having everything in html?
