It probably is true, wabe. And, you make a good point about the underlying architecture for the software - it has to be intended (and developed) to support plug-ins. However, in this case, Vue already has the basic import functions, and xfrog already has the basic export functions - so, we know at least one set of the file format conversion processes exist. I'm not really kicking about about this. Looking at this thread you can see how many of us are really interested. Rather small market, no?
