conformance test suites (e.g vobis, theora)

hi,

does anzone know of a conformance testsuite e.g. for vorbis and theora
bitstreams. This would be nice to have when e.g. testing a dsp based
reimplementation.

Also a testsuite that does robustness testing on the ogg container format would
be nice. If none of these exist, wound't that be a good project for e.g. next GSoC?
