My understanding is that 'estimate client' actually invokes the backup 
program itself to get the size estimate (so, `tar` or `dump` in most 
cases), while `estimate calcsize` calls the calcsize program instead, 
which does some lookups that are significantly faster in most cases than 
calling out to `tar` or `dump`.

Either way, both of them require running arbitrary commands client-side, 
which is part of why ZWC only supports 'estimate server'.
