jcl, I just want to say it's disappointing that you never responded to this thread, even if it's not a surprising outcome at this stage in the community's history.

This thread saw lots of good data and support, and the only naysayer(s) here settled on the argument that you know the market better than us (reasonable), which comes with the (unreasonable) argument that you know the market better than the developers of much more successful commercial engines, as well as very successful independent games, who not only support more desktop platforms but attribute much of their success to that support (yeah, we didn't make this argument without sources).

A "no, this isn't feasible and is not planned for the foreseeable future" earns more respect (or, depending on the reader, less disrespect) than ignoring the thread altogether.
