Takashi-san's description was not very clear, but it sounds like it's a patching mechanism for userspace applications - not for kernel space. So kprobes would not be a good fit.
If I'm right, I'm not sure why some of the bits of it were done separately instead of via the existing ptrace mechanism. And GDB would appreciate a mechanism for mmap/munmap/mprotect in a debugged process, also.
