The DriverPacks integrate into a Windows source of yours.
Do you want us to offer A Windows disc somehow?
I bet it wouldn't exactly make MS rejoice...
As of now, if you DL BASE and the DriverPacks, you can make your very own Universal Driver Disc - what would yours offer over the current solution?
Also, as you may know, some packs are updated quite regularly.
Having one disc image would mean to update the whole pack and make each user DL it after each and every update.
Granted, we could work with xdelta files, but still, you'd need to get the whole thing at least once.
As of now, users on a low bandwidth connection can chose not to include packs they do not deem necessary.
Also, you can already donate to the project if you like it! 
If you wish, also on a per download basis
