My colleagues from the engineering dept ( I am IT... ) have to use a 
commercial application which comes as 2  CD images plus 3 sets of 2 isos 
with updates. All of which have to be installed (at last theoretically ) 
one after the other and only via their own Java-based installer.
Guess who is not going to rpm-ize the process of installing that 8*450 
MB piece of wonderful software.

And by the way, there are 50% chances that this piece of software was 
used in the process of design of your phone. At least if the phone was 
engineered after 2000.
