[PLUG] Creating a large, multiple device read-only file system

["K.S. Bhaskar" <bhaskar@bhaskars.com>]

I realize that I can create a medium size read only file system on a DVD.  Performance is not a concern because the OS buffer cache will keep frequently used bits in memory.  But what if I want to create a truly giant file system.  Can I take 20 5GB DVDs and create a multiple device / logical volume that gives me a 100GB read-only file system?  Any pointers are appreciated.  Thank you very much, in advance.

P.S. No, I don't have a specific use scenario - this is for a conceptual design / thought experiment.
