kexec proof-of-concept and Verizon SGS3 bootloader bypass
Team Epic normally focuses on Sprint phones, however the great similarity between the SGS3 LTE variants like Sprint, T-Mobile, AT&T and Rogers has made it possible for us to publish CWM recovery, root .zip and other tools that work on all these phones. Unfortunately, the Verizon SGS3 LTE variant locked down its bootloader to prevent customized boot kernels. mkasick's kexec for SGS3 LTE should allow other developers to create custom kexec-enabled kernels for the Verizon SGS3.kexec benefits for Sprint SGS3 (and T-mobile, AT&T, etc.)
kexec will soon allow us a convenient way to multiboot into alternate ROM's. For example, after CM9 for SGS3 LTE becomes available, bbelos will have a toolkit for you to install CM9-on-EMMC. http://www.epiccm.org/2012/06/sprint-sgs3-cm9-development-plan.html
