Speaking of ResEdit, does the resource fork still exist in modern MacOS incarnations?

I still remember that I used to rip the graphics of Escape Velocity (Nova) by simply copying them out of the resource fork of some file (was it the executable itself?).

I also remember that my teenage self had a hard time writing a utility that copied files over a network, since I had trouble serializing the resource fork (or coming up with the idea of serialization).

Last time I checked, the filesystem (HFS+) still supported resource forks, but in OS X they're neither necessary nor sufficient for their intended purpose. In classic Mac OS this was the only way to bundle parts of an application together and present them to the user as a single file. In OS X, that's done with plain old directories.
