AFAIK, the only 2 ways to flash anything to a Kaiser is through the SD card or USB port. Noone (to my knowledge) has ever created a RUU-flashable Android package for the Kaiser or any other device, which would be your only option.
Given the constraints on the RAM built into the Kaiser, you would have to build a pretty small package for the install, maybe 55-60MB, use Oli's NBH creator and (hopefully) build an installable package that can be sent via USB with an unsigned RUU updater.
If someone wants to take on the task of stripping an androidinstall package, extracting it and repacking it into a RUU installable NBH, feel free. I know it can be done with a kernel package, but that is only 3MB and goes to the first partition. All the other files would have to go to the correct partitions as well (/system, /data, /cache, etc.).
