I'm sure it could be done but I for one have not followed that thread.
You mention a charity org, why use MS when the supported backend can all be run on free server apps?
I'm no fan of MS and have no desire to learn more than I do. Big job with limited needs for any hosted sites.
BTW, you can easily install MySQL on an existing MS server that also runs the MS SQL server. MySQL isn't a pig and is happy alongside other servers.
