This is pure speculation in my part:
Web-based player view is one of the (if not the) next major hurdles for LWD. It's probably going to be a prime focus of upcoming development. Just don't forget that the content market and community repository are means for LWD to monetise RW, so they're hugely important, too.
On the plus side, it's a simple problem: turn all of our cloud-synced realms into pretty web sites.
Unfortunately, simple isn't the same as easy, and there's undoubtedly a heck of a lot that needs to happen in the background to make sure it works right.
And there's also all of the other "essential" features (calendars, journals, and export, I'm looking at you) that the survey will hopefully push front and centre into LWD's development plans.
So, since it was a selling-point, it's on the horizon, for sure. How far away it is, though, is something only LWD can really address.
