        !            30: <LI><B>Why can't I run the LON-CAPA system on a Sun Microsystem, 
        !            31: MacOS-X, Windows-NT, or a LINUX-based system other than RedHat 6.2?</B>
        !            32: <BR>The short answer is you can run LON-CAPA on most any type of 
        !            33: computer, but you shouldn't.  The software system of LON-CAPA has
        !            34: been designed with security and performance in mind.  Unless you are
        !            35: prepared to understand the configuration details of the LON-CAPA network
        !            36: layer and security issues specific to your operating system and machine
        !            37: architecture, you will not be able to run LON-CAPA.  In the long-term,
        !            38: alternate scenarios of running the LON-CAPA system will add significant
        !            39: administrative overhead in terms of LON-CAPA software upgrades.
        !            40: <LI><B>What about firewall configurations?</B>
        !            41: <BR>Firewall configurations are doable, but not recommended.
        !            42: This requires detailed understanding of the LON-CAPA network layer, reduces
        !            43: network connectivity, and may require reconfiguration upon new software
        !            44: releases
        !            45: <LI><B>What about load-balancing hardware configurations?</B>
        !            46: <BR>The good news is that LON-CAPA supports its own load-balancing
        !            47: of web-delivered content.
        !            48: <LI><B>What about backup tape drives and CD-ROM burners?</B>
        !            49: <BR>There currently is no defined system of backing up LON-CAPA resources.
        !            50: It is, however, both easily doable and highly recommended.
