Consider a different use case:
I'm using Cygwin (unix environment within windows),
TortoiseSVN from within windows explorer,
a Linux installation within a virtual machine (vmware),
and sometimes switch between the Windows and a real
Linux installation. They all share one disk partition
'for code experiments'.
The total amount of WC data is around 2GB. Its very nice
to 'share' modifications between all this envoronments,
instead of doing immediate checkin/checkout to the
central server (I also have a very slow access to the central
repos...) -- multiplying the 2G by 4 wc's and using
checkin/checkout for every fix would slow me down
quite a bit.
