Fading from one texture to another.

Let's say I have a cube which has a texture on it.

I then have another texture which I load sperately.

Now I want to gradually switch between the two textures so as one fades away the other one becomes more prominent. So they would both hit alpha 0.5 at the same time.

I know I can multi texture to get both textures on the same object at the same time but how can you adjust the alpha of a texture on the fly (i.e. fast enough to do in realtime).

I tried EntityAlpha but as expected it doesn't work for textures.

Anyone done this already?

Thanks,
