I have local patches submitted by Chris Faulhaber to copy ACLs when a file is copied (or moved between file systems) that I've been meaning to finish testing and merge. Likewise, for gzip, bzip, and others when a file is replaced. This wouldn't address the general issue of copying extended attributes, but is a necessary step. Presumably if we did extend cp, et al, to copy EA's, they should explicitly copy only user namespace EAs, not system EAs. There's been some recent e-mail on the Linux side about interfaces to copy ACLs from one file to another, but I haven't had a chance to review those changes as yet to see whether we should pick them up. Using the current EA interfaces, it should be relatively straight-forward to generate a list of user EA names, extract them, and copy them to another node.
