Greets! First post... I've been reading about SB having just recently learned it existed! It looks like a very cool language to use (I really like BASIC style languages), and I'll certainly be evaluating it for an upcoming project I have in mind. Currently Tcl/Tk is the front-runner but SB along with Gtk-Server could replace it.
That being said, if you wish to generate more interest in SB, how about an OpenGL binding? Seriously. Nothing gets attention like the ability to program graphically oriented programs. An OGL binding could attract interest in the gaming world (the script kiddies and game programmer wannabes LOVE this stuff) not to mention binding to a world class, cross-platform graphics API.
Worth considering?
