So do you think the following statement is roughly true?

"There is enough similarities in the needs of these broad industry 
segements with respect to communications requirements/needs in emergency

a) Protocols can be enhanced (or in some cases developed) to handle the 
similarities, while

b) Differences are relegated to implementations or behavior descriptions."
