Cloud computing in a bunker

There has been some problems with cloud computing, from the day when S3 went down, to the day when I flew to London.
On the former I have shared my thoughts, but what reinforced my opinion that we are far from the days of Cloud computing was the weekend in London, when I tried to send an e-mail with an attachment to a co-worker, and the only place I could do it was from home, after I returned from England.

Now, there are a lot of WiFi in London, that’s true. There is The Cloud, BTOpen, T-Mobile, etc., and yes, if you are on a business trip you probably can afford the prices – 2p per minute for BTOpen, or 5 pounds for 30 minutes at T-Mobile, or you can you register with them and get a regular subscription – however there is still one problem left.

The quality of the WiFi is incredibly low. I paid for the WiFi at the hotel, and in theory I had internet access, but it was so slow that it took about 40-70 seconds to load one simple page, so I gave up.
I went to several Starbucks, and I went to Wetherspoon – I heard they have free WiFi access, that day they did not have -, and I tried, and spend actual money on the internet, but I had limited resources so to speak, so after it turned out that even the paid WiFi is uselessly slow I gave up, and sent the mail after I got home.

So, yes, theoretically I could keep all my stuff on the net. I could compute in the Cloud.
And when I am not at home or in the office with a broadband, I can rest without any worry that I will be e-mailed to work in the Cloud.
Because there is a good chance that I will not have any way to fly that high.
