How about using (non-alchohol) jello shots? I don't know Jack about making them, but the idea came to me after reading the first thread.
Make some jello shots, scoop out the center, pour in the right amount of 'foul tasting powder', throw the scooped out part back on top and there you have it. This will taste good, probably not many calories, some carbs for pre/post workout and it's very unlikely to ever touch your tongue.
