I've been attempting to answer my own questions here by Googling around, and I must admit that this is a highly frustrating experience. I have rather extensive computer experience and I'm finding a SAGE server maddening to set up. Do normal mathematicians find this easy and I'm just being boneheaded today, or is SAGE server setup only for the ultimate in Unix ninjas?
For instance, the best two resources I've found are (a) Dan's post mentioned earlier in this thread (about which I still have unanswered questions that are keeping me from succeeding in that direction; see earlier in this thread), and (b) a post by Luiz here: http://markmail.org/message/aovcanxgna6alwvs but in replies to it, William Stein throws out numerous corrections, some of which include frightening comments about how everything will be brought down by a malicious user if you do X instead of Y. If the terrain is truly this perilous, why is there not clear documentation on how to set this up? Is this not a crucial bridge anyone must cross if they hope to adopt SAGE for classroom use? Is it truly the case that SAGE is as mature and well-known as it is becoming without a tutorial on how to set it up for a class of students to use? I'm hoping that perhaps I just haven't Googled correctly, and someone can point me to the right doc page that I'm just not seeing.
