I'd heard about http://modern.ie and tried it out a few months back. It seemed to be a lot more reliable than using IETester via Wine and generally a lot easier to set up.
I wanted to try out the hangout feature of Google+ which requires the Google Voice and Video Plugin, but when attempting to install the plugin using the downloaded rpm in Fedora 15, there was a worrying number of dependencies. This is how I fixed it.
