Why do you think that's necessary? It should detect corrupted images 
because it checks to make sure that gunzip doesn't fail on them before 
installing (CRC). That doesn't protect against compromised images of 
course, but I don't think we're far enough that we have to worry about 
this yet. :)

I might consider compiling m0n0wall's PHP version with OpenSSL support 
and then do real public-key based verification of the images. That would 
also eliminate the need for network connectivity to check the 
authenticity of an image.
