Thomas,

Live has to expand to the date when the sources were fetched, otherwise 
its not 'live' by definition.
As an illustration, I install KDE 4.2 on my 25MHz 486DX with 64Mb RAM.
During the time it takes to build, 'live' is likely to have changed 
several times.

How do you handle prefetching of sources, or do you forbid 
prefetching ?
Live infers you fetch the sources at the time you need to build them 
and do the live expansion at that time. Without that you don't know how 
old your live version is.

live can change several times a day. With only one day resolution, how 
do you handle that?
