I still actually like Kool-aid so I use the presweetened type repackaged w/ a small, ~2oz plastic bottle w/ a screw-on squirter cap.

Kool-aid is available in the same single serve packets that Crystal Lite is available in. You can also get various instant ice-teas (like Lipton) and, as mentioned above, sports drinks in the single serve packets. Target seems to have a good variety of single serve drink brands.

Of course, this doesn't solve the waste problem. But, at least for those who enjoy kool-aid there is an option.
