I can see that from my previous question and a few other's questions that there is interest in getting SEO tools for Excel working on a mac. I know for a lot of users purchasing Parallels/VMWare Fusion is another added expense that people don't want to buy to use your software. As a developer, I do most of my development using Vagrant & VirtualBox. While running Windows using Vagrant on a mac is an absolute nightmare, there may be a nice middle ground that could help users.
Do you think there would be interest in creating a VirtualBox image that would have Office/SEO Tools for Excel pre installed and a shared folder to the mac? If there is interest i'd be more than happy to help create the image. The only thing i'm not 100% on is how the licenses would work - though I know that Microsoft provides Windows VMs on Modern.ie - so there has to be some way to do it.
