Some of us aren't even sure we are ready to install plain old Lion on our production machines yet :-)

Disk drives are so cheap that no one should experiment on their production system without a safety net. Clone the disk with SuperDuper! or Carbon Copy Cloner, then try out new operating systems on the clone. At such time as you switch to using the new OS, use the extra disk as a clone backup, updated regularly. Good news is that some of the Omni developers undoubtedly have installed ML and are probably hard at work on finding out why OF doesn't work.
