Hi,
Yes, this will work fine in theory, I have successfully served content from Apache using a file system mounted in memory. I think a PHP cache/accelerator would be a better option though as it will save the files in memory in their compiled state.
As long as you populate the file system after each boot you can treat it as a normal disk. You can write to the files, but obviously your changes will not persist across reboots unless you move the data to a hard disk.
PS: nice sig
