freeware != free software, but lets look at the rest....

bang, non-free.  if we distribute this, and commercial entities
distribute/sell debian CDs for profit we have just violated this
licence i think.  it fails DFSG 6

also it makes no mention of allowing modification of the source, or
distribution of such modifications.

this is documentation rather then licencing it appears.  the the
mention about being easy to incorporate into other programs suggests
that modification is allowed, but that is an ambiguous leap...  the
non-commercial use only clause above already makes it non-free
anyway.

define `use'  see also the recent debacle about ipfilter on *BSD.

yes i think MacBinaryIII is public domain, but we must find some sort
of licence or statement to that.

whats wrong with a binary file?  all the floppy images are binaries
too, that doesn't hurt anything.  in todays modern network 6-bit ascii
encoding is no longer required or necessary (in most situations, smtp
transfer is one exception).  it is in fact less efficient do to the
larger file size.

*if* we find a free software debinhexor or unmacbinarizer we can store
it in binhex or macbinary format in the archive and modify the CD
image build process to handle that file so long as it doesn't cause
any other problems.  then it will be usable from the macos side of the
CD.  *nix has its own tools for this purpose not that it matters since
macos binaries are unusable.  

note its been suggested in the past that we use self extracting .sit.
this is also not an option because:

1) the self extracter is very proprietary and non-free
2) the self extracter has a strict licence prohibiting commercial
distribution, unless you pay aladdin a truckload of money for a
licence.
