Unfortunately I think the only answer will be "detect those hosts and disable zoom".
The tab thing is easy enough sure. I find it handy enough in logic but we can easily make it a user option; or disable it in FL if I can detect the host identify easily enough. The best workflow is "open an issue and we will close it in an upcoming beta" or if you want "code up the fix" (which in this case is just removing the tab key). The tab key caused us other problems too so I'm not that attached and don't think anyone else is either.
