Just one more advice. Choose CF cards with adequate data rates for 
write. My experience is that during writes the card isn't accessible for 
reads. Therefore IPCop  sometimes seems unaccessible from the Web GUI or 
the shell. If you minimze the writes thats no problem, but if you use an 
addon like Update Accelerator it may be an issue.
