The main issue I see regarding a live installation process is the fact 
that the LiveCD has been stripped from several files in order to reach 
the 700MB target. Language and documentation files are removed to give 
some space for OpenOffice.org. As a result, the LiveCD environment is 
different from the one obtained via the normal installation process. 
While this should not make a difference for English-speaking users, 
others may be confused by the missing files. This could result in more 
load for the support channels as they will have to explain why package 
xyz installed via the LiveCD is different from the same package 
installed via RPM.
