" ....add-ons for poser"
I suggested a while ago that a modular type of system (like C4D) could keep costs down and give people what they want.
For example, if you never want to use the hair room (module) it should be an add-on to buy if you want, or don't.
That is, a base Poser program where you only buy the modules that you want to use,  instead of paying for "rooms" you never go into.
This of course, would require a complete code rewrite. Heaven forbid.
