I think this issue really harms the broad utilization of EPESI over the long term. I'm not a huge IE fan, but 100% of my work is tied to US mid-size companies and there are few corporations that don't standardize on IE. Many are now allowing alternatives, but now that IE 10 is on the standards train (more or less), it seems like we should be able to mitigate functionality issues.
I know you don't have a Windows machine. Is there something I can do to assist in the discovery / documentation / development of solutions making EPESI a little more IE friendly?
