Hey Natalie,
Thanks for reaching out here!
While there unfortunately hasn’t been much further progress on this specific issue, I’m curious if you’ve tried out this extension for WooCommerce? → http://www.woothemes.com/products/name-your-price/
I have not tested that myself, but I’m sure you can get a refund for it from them if it doesn’t work very well. Double-check with them about refunds for that specific add-on just to make sure, but if they are generally cool with refunds and would grant you one within 30 days after purchase, then it might be a great idea to try out that WooCommerce add-on, see if it works well with Tickets on events on your site, and either keep it if it does or get a refund if not.
I hope this news isn’t too much of a disappointment, it’s the best solution I can currently think of though. Let us know if it helps at all!
Thanks,
George
