Confused with NetBoot

So I am currently planning an integration of macs into our current PC infrastructure. We will be doing a mixed server enviroment, with user authentication done in active directory, and desktop restriction through workgroup manager and open directory. I am currently looking at ways to handle imaging (installing OS and apps) our new macs. When I originally read about NetBoot, I understood it as basically a clone of Remote Installation Services (what we use to image our PCs), but now that I have come back to it I understand it as all machines boot off of a network image. This will NOT work for us, as 95% of the mac clients are ibooks connecting wirelessly, and running a network os to them would bog down our network. What solutions are there to install a preconfigured OS and software package to mac clients over a network?
