Buying VMWare Fusion

Hi, I hope I am at the right forum here.

I have an imac and a macbook.

I bought Fusion 2.0 in 2009.

I updated to 2.0.8. This no longer works if I wish to upgrade my mac to mountain lion.

I cannot automatically upgrade Fusion to version 5 so I have to buy it again.

A few questions on that:

1. Do I receive a DVD package or just a download.
2. Can I burn the installation file on a DVD
3. The comparison with Parallels suggests that you can use the single license for 3 Apple devices. Is this correct?
4. Can I export my iMac virtual machine to my macbook and use it there as well?
