yes this is doable. You need to set the internal format to something like: GL_RGBA32F

and the source type to float on your texture.

You might look at the OSG forest example, and its use of osg::TextureBuffer. Basically with the forest example, its doing instancing where the transforms are loaded into a texture, and the data is used in the vertex shader.
