LBGSHI has posted an update on his Project Artemis:

Project Artemis is an endeavor to create an open-source, free PS2 application, using the PS2Dev.org unofficial PS2SDK (a pre-built version of which can be found at GSHI.org , entitled, “Win32 PS2SDK”), that will allow a user to dump PS2 memory repeatedly during game play (either to a USB flash drive, or remotely via a network cable to a PC), so as to compare these dumps (either on the PS2 itself, or remotely via a network cable to a PC, using a compare utility), and the ability to force specific memory addresses to hold specific values (in order to test results of searches). The end product will be a fully-fledged RAM-hacking system and remote debugger, which will allow users to create their own cheat and enhancement codes for games, and debug games and applications.

Thanks to Jimmikaelkael (and to several others, including ffgriever, misfire, and Polo, for providing useful information and source), we now have functional in-game memory dumping capabilities (dump to PC), for about 50% of all games (and increasing rapidly). Check out the SVN repo for details and downloads
