Now still the question -- will one be able to buy a perpetual licence? Feels doubtful.
From their FAQ (emphasis mine)
Will the cost of my membership ever increase?
When you purchase directly from Adobe, the cost of an annual membership will not go up during the first 12 months of your membership. It is possible that the cost of the month-to-month membership will increase, but if it does, you will be notified and given the opportunity to cancel.
Adobe also offers prepaid cards through retailers and resellers that allow you to buy membership with an upfront payment.
Can I prepay for my Creative Cloud membership?
You can prepay for one year of membership when you purchase through a retailer or etailer (like Amazon). This gives you the same price as purchasing an annual plan directly from Adobe, but you pay up front instead of monthly.
And as to the desert scenario:
Do I need ongoing Internet access to use my Creative Cloud desktop applications?
No. Your Creative Cloud desktop applications (such as Photoshop and Illustrator) are installed directly on your computer, so you won't need an ongoing Internet connection to use them on a daily basis.
You will need to be online when you install and license your software. If you have an annual membership, you'll be asked to connect to the web to validate your software licenses every 30 days. However, you'll be able to use products for 3 months (99 days) even if you're offline.
So, a bouncing Adobe Validator icon in the dock every 24 hours? I already have to deal with something similar at work. Only IT can be an administrator on a Mac, so every time anything updates or needs to connect to the web like this I am screwed. This is a productivity suck, but one which will happily be balanced out because I'll be connected to the people I collaborate with and the people who inspire me. Unless I'm offline.
