Let's develop an open-source media archive standard

Rumor has it that Jules Richardson may have mentioned these words:

Different systems interpret binary data differently, especially if there is
human-readable code within the file. MS-DOS very likely could think the
file is binary, and the first hex 0x06 would terminate the file. However,
if it is considered binary many viewers wouldn't open it if it's got
non-printable ASCII characters within.

Or -- how about transferring this file from MS-DOS <=> Linux <=> MacOS <=>
BeOS ... will it (and if so, how will it) convert line ending chars, tabs &
other binary chars? A hex representation will reduce conversion problems
measurably - remember, this is supposed to be an "ultra-portable" format.

Not necessarily - IIRC, Moto S-records only have records for where there's
actually data, right? So if the disk is only 1/2 full of data, the S-record
would reflect that, right?

If we're already going to take this "beyond" the spec, couldn't we
institute some RLE encoding as well?

Just thoughts,
