3dvia's main argument for a long time was it was free. If your goal is to get more premium members, that's fine. But I think if some of 3dvia's main purposes are for premium only, that isn't right. 3dvia is supposed to be fun for everyone, and things like embedding scenes, uploading private models just so you can take a look at them in the player, and converted DAE files, and so many file formats, and all the other features, are one of the main reasons to choose 3dvia over Google to start with!
If you limit it down enough, the only things separate from the warehouse are the comments, the blog, the player and software, and all the things 3dvia already had right when I got here! You've come this far with 3dvia's cool new features, and if people have to pay for it, 1. you have wasted all your programming because no-one except who's paying for it can use it (limiting it down to about 1/10 of the users), and 2. it's not as neat anymore! I can't tell all my friends to go to 3dvia because it CAN convert models to DAE, and it CAN embed models in sites for free, because it can't!
I'm sorry to throw this in here right after you have upgraded me to plus. I'm thankful you upgraded me, really, and I realize you probably won't change it back. But to pay $99 a month for something that was free for a year and was going so well is a pain!
