Projective textures

Hi... We are trying to make a flashlight for our game. We tried this resource but it didn't really look like a flashlight to me.

So I did some research on how to simulate a spotlight and all the stuff I've found is very similar to this
http://www.opengl.org/resources/tutorials/advanced/advanced96/node27.html.

After a lot of hacking in the engine, I finally found a way to make the three passes work and a lot of hacking later I managed to get it working the way it should. So, now I have the flashlight working, but I can't place it were I want it to be. Here's the relevant piece of code:

glMatrixMode( GL_TEXTURE );
glPushMatrix();
	glLoadIdentity();
	glTranslatef( 0.5f, 0.5f, 0.5f );  // We should use this line, but it works better without it...
	glScalef( 0.5f, 0.5f, 0.5f );
	gluPerspective( 65.0, 0.75, 0.1, 2.2 );

	MatrixF mProj, mView;
	dglGetProjection( &mProj );
	dglGetModelview( &mView );
	mProj.mul( mView );
	mProj.transpose();
	glMultMatrixf( mProj );

Doing that, before the second pass, makes it look like we have a flashlight placed on the camera. But we want it to be on one of the player's mount nodes. According to what I've read, I should, then, apply to the texture matrix "the inverse of the transformations needed to move the light source away from the eye position".

I have the mount transform and the current ObjToWorld matrix, which, I think, are the necessary matrices to get where we want, together with the current model view. But I really can't make it work . :-(
Another way to do it would be to use "gluLookAt()" after the call to "gluPerspective()"... I have the flashlight position, and the it's direction... So calculating all necessary vectors is easy, but I can't get it to work either... :-(

So this is where I'm stuck... Can anyone give a helping hand here? I've been trying to make this work for quite a long time now. I didn't find anything on projective textures in the resources, nor the forums.
