Automated testing of installability of foreign architecture packages?

[Scott Ritchie]

wine1.4:i386 is currently not installable on amd64, although 
wine1.4:amd64 is.  I would, however, like it to be, for a person who 
wanted 32 bit only Wine even on a 64 bit host OS.


It occurred to me that, while Britney is automatically testing 
installability of packages, we may not be testing cross-installability 
like this.

Shoudl britney be extended in this way, or does down this path lie madness?

Thanks,
Scott Ritchie
