I’m just in the process of releasing an experimental version (0.9) of YAK which showcases the latest features, such as product options, removing the need for exec-php, a credit card payment form, and a few other requested changes.
This release should be viewed as -highly- experimental. If you release it into a production system, you are, quite frankly, raving bonkers and should be committed to the nearest psychiatric institution.
That said, hopefully someone will have a test system that they don’t mind trashing, and get back to me with some feedback. Check the main YAK page and you’ll note that the way you use the plugin has changed (using html comment placeholders instead of php function calls using exec-php), so upgrading will unfortunately be a time-consuming process. WARNING: documentation may not be quite as comprehensive as I’d like.
The next stable release of YAK to include this functionality will be the 1.0 release, but is unlikely to be out before Christmas, because I need more time to fully test the new features.

Great!
