Flashgun technologies have come a long way since Vivitar first rattled the world with thyristor circuits on their venerable 285 speedlite. Today, advanced circuitry can slice and dice your flash exposure into exacting portions to light your subject regardless of its level of reflectivity.
Camera-mounted speedlites can be lifesavers when you're shooting under low-light conditions, but if you wish to avoid the "blast-in-the-face" lighting effects of on-camera flashguns, you're pretty much limited to bouncing and diffusing. If you're looking to expand the abilities of your speedlite you should have a look at the new Dot Line RPS Studio Speedlite Accessory Kit.
