I.
I think it's very important maintaing windows diskless guests.
If we have lots windows guests could be very important maintan them  
using a single image.
Windows diskless is very different vs linux diskless.
Using VhdSoft or neoware image manager, you can make a single image  
for all windows guests (for example a 8GB image).
Each windows guest which boots from network work on the single image  
and store a differencing cache image on the storage.
Firstly you can avoid to duplicate 8GB for each client.
Secondly you can handle updates on a single image rather than on each guest.
Thirdly you can decide to setup each image in administrator mode (to  
add patch or software), volatile mode (each modification is lost at  
next reboot), persistentg mode (write cache is not lost at next reboot).
This technology could be used for physical PC, but it is very very  
usefull for virtual guests because virtual guests have the same  
hardware (so you need a single image).
In other words I would be to make a Virtual Desktop Infrastructure  
saving money for storage and maintenance.
Are you agree ?
