Charlie, I suggest that you read the Rademacher paper, as well as some of
the research upon which it was based:
Subletale Wirkungen von Oxalsäure in Kombination mit
Zuckerwasser oder Glycerin auf Apis mellifera: Untersuchung
der Toxizität, der Pharmakodynamik, des Verhaltens und der
Lebensdauer, sowie der Rückstände auf Bienen und
Beutenmaterial

Unfortunately, it's in German, but worth going through.  Available at
http://www.diss.fu-berlin.de/diss/servlets/MCRFileNodeServlet/FUDISS_derivate_000000018264/Schneider_Saskia.diss..pdf;jsessionid=5321E44F4CEBFF4AA61055B06BDF0348?hosts=

Schneider and Rademacher have been investigating alternatives to sugar as
humectants for the OA dribble, and have some good tracking data.
