This is my last comment on this thread, since you keep repeating the same unfounded complaint. I did mention the extra measure of moving coins offsite in my original comment (which is trivial if you know how to use cron). As long as you do this, your risk of exposure is the amount of Bitcoins you accept during n interval, where n can be practically as small as you want it to be.

Also, I get the distinct feeling you're lecturing us about something you've never done. "to operate [a wallet]"?? "to transfer fund just there, either keys or source code capable of replicating it"?? How would you connect a web app, say a Ruby on Rails app, or a Django app if you're more comfortable with Python, to Armory to process Bitcoin payments? There's a new feature that's just been merged that I see would allow Armory to be used on the web, but as far as I can tell, no one is using it in production. But assuming this feature is production ready, how would you use Armory to process payments on the web? Have you actually done this? You're just mentioning a product and nothing about implementing payment processing. The extra measures needed to set up payment processing are most decidedly non-trivial and should be detailed.

Finally, I should mention that Bitcoin Armory is under AGPL (even stricter than the GPL), which means that no serious business is going to use it for payment processing since they would have to open source whatever app they are connecting it to (it's just fine to use it to store a business's Bitcoins, however, since in this case, it's not connected to your application). From the BitcoinArmory site: "Armory is licensed under the AGPL version 3, which guarantees that any derivative programs based on Armory source-code must also be open-source." bitcoind, on the other hand, is under the MIT license and can be freely used in commercial software without the obligation to share your source code.
