at the SRND and you are ok with the backend servers, albeit you are going to need some big servers… to enable all the students, but expressway doesn’t appear to scale to your scenario. Albeit I’m frankly going to guess in a real world scenario you aren’t
going to hit close to that 25k number you are positing.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:black">My concern with the scale is this: If we deploy this to all our students, they will install the software on their laptops and mobile devices and that software will
continue to run when they leave the campus and go home. Some of them will want to continue to use it actively, but others might just have it running in the background. Not sure if there are timers that log people out, but it was my understanding that Jabber
has been modified to keep them logged in always. This means, those 25,000 active users on campus, now become 25,000 active users off campus.<o:p></o:p></span></p>
