@williamrochira: Not really, the last time something remotely like that has been done was on FW 3.x, and it involved hard java bytecode tweaking, which is NOT a recommended way to delve into Kindle hacking, especially on a device like the PW2 with flakey recovery capabilities at best (unless you have serial access).
I linked to the 3.x stuff a couple of pages ago, and dsmid has posted a few relevant stuff since, too.
(Plus, I'm not a Java guy anyway
).
