I just installed FreeMCBoot on my PS2 inspired by @Elizafox and I'll hopefully try running some games via network really soon :). Even though my PS2 has a modchip already I thought softmodding it with FreeMCBoot is much better. That way I don't have to boot an elf launcher from a CD whenever I need it. Any attempt of making my PS2 use less and less it's DVD drive it's right up my alley ^^.
