[plug] is rsync not good for iso updates because highly compressed - whole image changes if only few updated files?

[Daniel]

Hello All,
I envisaged rsync for situations like when a beta of a new distribution 
release comes out and is shortly after superceded.
I have been told that even if few files are changed the isos are so highly 
compressed these days that the files appear totally different to rsync and 
thus the whole file would end up downloaded.  Is this correct, or is it 
only with some distributions?

Thanks very much,
Daniel.
