MAT poses are just text files (as are MC6 files). Even with thumbnail PNGs, when compressed into a ZIP file they are very small (even for a large number of MAT poses). These could be included as seperate ZIP files in the installation file for a product/freebee, and the end-users could install which or both that they want.

Granted this would take a little more work for the content creators, and a little more work for the end-users, but everyone could have what they want. And once made, there is no more work. Except of course there would be the neverending questions to answer about "where are the materials?", for those who do not read the documentation.
