Hey Jian, First of all, I would like to say that I do not know all of the nuances of all the requirements. That said, I think that it would be rather difficult (if not impossible) to do a full install just as a regular user. Depending on how much experience you have with Linux (or Unix) systems, this could become even harder. The strictly Koha stuff (i.e. the files that we have on SourceForge) should no present any problems being installed in a user directory. The hardest part will be getting the Apache and MySQL stuff set up if you do not have a root account. I really think the best way to play around with Koha would be to either use the "Test Drive" installation at http://www.koha.org/drive or to put Linux on a machine that you have and then install it on that machine.
