The funny point here is that the license effectively may lead to a
situation which disreputes the IAU: someone can just start a compatible
version of SOFA, starting f.e. from the (GPL version of) SLALIB, and
using the iau_ prefix. Since all functions APIs would then look like
SOFA, a bug could be misinterpreted as one in IAU code.

I could probably (re-)start some discussion in Debian-legal about the
current license; however this is a bit of Harakiri. Especially since
Wheezy is soming soon, there is a danger that SOFA , AST, and DS9 will
be excluded from this next stable release.
BTW, since the SOFA license is incompatible to the GPL (which is the
license of AST and PAL, which both depend from SOFA, and include its
source code), the Starlink group should also be interested in a license
change of SOFA. Currently, a binary distribution of AST and PAL is
illegal since one cannot provide all its source code under GPL.
The same belongs to DS9; formally their binary distribution is illegal
for the same reason. They however seem not to care.
