You can make it into an injection file. It is much smaller that way. What you have to do, though, is edit a pz2 to use your delta information and one of the blank channels that Daz provided in V3. An easy start is to take an existing inj pose, replace the delta information with the delta information of your new morph, and change the morph name to one of the CC-# channels. There are some pretty good threads on this over at PoserPros, and I am working on a tutorial, although I have been swamped, so it is going slow. As far as I know, there is no problem with distributing a morph obj, as long as it is stripped and is all your custom work. :D
