To come clean over my reservations regarding RL identity, the one and only sticking point is the fact that I am an aspiring RL 3D designer, and for better or worse virtual worlds currently carry the stigma of "amateur" and "possible sexual freak". I certainly don't rule out moving into adult items when conditions in the market improve.
I hate that stigma as much as anyone else, but If I go to an interview with my portfolio, I am sorry to say that at this point nothing I have ever done thus far Virtual Worlds would feature. Its a sure-fire ticket to awkward questions and implied assumptions.
"So Mr Wayfarer, you like to dress up as a tree-man-thing in your spare time, tell us a little more about that...." Furries know exactly what I am talking about here.
Its not just the general public that think this way, many industry people do too. Paradoxically, it is exactly your observation of "right now, since many people still think virtual worlds are just games" that is the problem here, for me at least.
If this was my main breadwinner, then I would have no problem giving you all the details in the world, heck, you could probably even come over to my house and party.
But, sadly its not, and the real world currently takes quite a dim view of us virtual people. From professional considerations alone, that is enough for me to want to maintain a firewall.
