The problem is some files in the IDL generator belong to Sun Microsystems.
The license is incompatible with the Debian guidelines and, IIRC, it may
even be incompatible with other files in TAO.

An alternative IDL generator (C++11-based) has been under development for
some time but so far, it has not replaced TAO because it is incomplete.
Johnny may have more details, I think it was being developed by Remedy.

IIRC Debian Policy does not allow that. If your source package is in
contrib, then binaries belong to contrib.

That's an alternative we would rather avoid because most users do not
enable contrib, therefore, they would never get to know ACE.

ACE+TAO is a complex beat to maintain. Currently, the debianbuild directory
contains essentially the official Debian packaging, which Johnny updates
from time to time. Prior to that, there was a broken packaging. In fact,
TAO is quite more complex to maintain than ACE.

Other alternatives:

5) Someone provides funding for the split packaging

6) Someone joins the pkg-ace-devel group and helps us do the splitting in
our spare time

The "all-in-one" source tarball is pretty convenient when building
libraries on Windows and to distribute yourself but is a nightmare for
distributions. E. g. I would like to package OpenDDS for Debian but it
requires such a huge effort (ACE, TAO, DAnCE, then fixing the OpenDDS build
system and probably source) that currently we do not have any DDS in Debian
or its derivatives :-(
