Not sure on the actor lines. I'd keep them in.
By the way I forgot to add a couple of lines of code to change in the cr2 above.

actor neck:1
{
storageOffset 0 0 0
geomHandlerGeom 13 neck
}

actor neck:1
{  
}

As to giving away the bodysuit for free. You can. What you have to do is:

1. Put the bodysuit, and the obj files for it in a zip file.
2. Encode the zip file (creating a rte file) using rtencoder (a free program) and the m4 base.
3. Anyone who has purchased the m4 base file, and has the free rtencoder progam, can then
       decode the rte file back into the original zip file.
4. Unzip the zip file into posers runtime dir.
