Hmm, the idea seem to be patented by Microsoft, i.e. this patent from
December 2002:
http://www.google.com/patents?id=cVyWAAAAEBAJ&dq=hotpatching
(and other patents by Microsoft if you search for "hotpatching").
And those patent descriptions, by the way, remind the way kexec works
("A software module is hotpatched by loading a patch into memory and
modifying an instruction in the original module to jump to the patch"),
which was released much earlier... In essence, they patented kexec ;)
