Yeah, I've hacked on the code in DEC's products before, and also know of the 
TGA spec which is basically what is needed to get the job done... Now if I 
only can manage to make enough time available to do the task... If anyone else 
wants a crack at it, I can probably provide a legit TGA spec. E-Mail me 
directly. Then again, maybe Joel is reading this list and wants to crank it 
out himself ;-)
