Collada importer/exported does not currently have maintainer so all the issues goes to the TODO list there http://wiki.blender.org/index.php/Dev:2.5/Source/Development/Todo/Import_Export

Thanks for the report anyway!

@BrendonMurphy, these reports aren't "duplicates" of each other.

We have a Collada project to collect these (see: https://developer.blender.org/tag/collada/).

Moved all collada reports into the "Collada" project, removed "Addons" and "Blender" projects.

note to self:
It looks like the export can be done in a straight forward way, see rna_Mesh_calc_tangents().
The FBX exporter does it similar to this:

me=bpy.context.edit_object.data
uvname = me.uv_layers.keys()[0]
bitangents=[0]*len(me.loops)*3
e.calc_tangents(uvname)
me.loops.foreach_get("bitangent", bitangents)

I add this task to my feature request list for now.
