Guidance in how to build the magic toolchain

wizards of InstaDMG, before heading out chasing rabbits trails I'd like to get some direction and suggestions as to how to create my system properly. My setup is as follows: - units distributed worldwide - very few servers to run bsdp from (if any .... depend on the willingness of the Network admins) - primary laptops - using InstaDMG to make the image used to install the clients - on top of the image there is a overlay system like Puppet that can complete the setup What I really need is some guidance in how to setup the tool chain from InstaDMG into Netinstall and all the way to the client. As well as how to best make the clients get the installation as they cannot use the broadcast protocol. Do I send a payload free package to each client that are running the bless command on these to get them booting of the install image. The location of the Install image will be distributed worldwide but not on OSX servers as we have existing infra for doing that already for other platforms. Hope that you guys can help with the understanding of how to connect the dots. Thanks.
