Thanks, Kyle. Your answer was very important to me. I am one of the few
guys in Brazil trying the use of OpenSim and have<br>
received, some days ago, a consult from an important brazilian university
asking me about the possibility of the creation of a 3D "virtual
campus" having many resourses, included the auditorium for 500. My answer
was: "We need to wait a little more to know if this is possible. My first
impression is that it is not an easy task to do it.".<br>
I am not an OpenSim expert like you but your answers confirm that
didn't say anything very wrong.<br>
