This article was posted to Apple's cocoa-dev mailing list. Perhaps someone here would care to clarify for the folks there why this is or is not possible, and if the "laziness" is really the issue, as the poster claims. Here is a chance to fight the FUD.

There has never been an issue with NeXT's distributed objects and endianness as far as I know.

NeXT's DO certainly worked seamlessly between
Openstep Mach on 68000
Openstep Intel
Openstep Enterprise/PDO running on top of Windows NT on Intel
Openstep Mach SPARC
Openstep running on top of Solaris SPARC
Openstep running on top of HP-UX on PA-RISC
I have foggy memories of possibly using NeXT's "Portable Distributed Objects" (PDO) on DEC Alpha.

The protocol deals with endianess internally. It probably just standardizes on one endian convention and automatically converts from the wrong one.

What has NEVER worked in distributed object between Openstep and Gnustep. GNUstep uses slightly different protocols and more importantly, the systems archive objects differently. DO between Openstep/Cocoa and GNUstep definitely does NOT work unless something has changed in the last year or so.
