I implemented a diskless filesystem last year for a project for a
client.  I did not have to write persistent data to the filesystem --
only temporary data.  I also had the ability to pre-load constant
files at system build time.  The application was an embedded webserver 
with CGI capability.  We talked about adding tha ability to write
flash at runtime, but there are timing issues and interrupt latency
problems when you do that, and we might have missed an interrupt her
or there.  :-(
