service implementation discovery support</title><prolog><metadata><keywords/></metadata></prolog><taskbody>

<context>       <p>For many service types it may be appropriate to build service

implementation discovery support. This will use <codeph>RApaLsSession</codeph> to

discover all applications that implement the service, decode their service's

opaque data fields from their application registration files, and present

the list to the client in a meaningful way. </p><p>For a chat service, this

could generate a list of service names presentable to the user in a list.</p><p>The

service discovery support must check the attacks from server applications

that pretend to be existing server applications, or prevent better server

applications from being discovered. Conflicts in selection could be presented

to the user, or automatic selections could be logged. The service discovery

support must reduce the amount of damage a malicious server application could

do through registration.</p></context>
