I really think you guys should check out several services that are here today, and even with current Amiga development tools (for OS3.9 or OS 4.0) are here today. They work great from python, php, and presumably could be scripting from the Amiga Shell/AmigaDOS.. Even if you consider the lack of a good web browser..
You should check out Amazon's web services
http://www.amazon.com/gp/browse.html?node=16427261They include things like S3 Simple storage that gives you online file storage that's available 24/7..
Other services include:
Amazon Elastic Compute Cloud
Amazon SimpleDB
Amazon Simple Storage Service
Amazon Simple Queue Service
You don't have to wait until 2018, you can have these kinds of things and do them today right from the Amiga (with TCP/IP and a Network card/Stack)..
Web services are much easier than a web browser to implement and return text or XML most of the time and work like a remote procedure call.. REST protocol seems like a slam dunk and I am suprised no one has done stuff with that yet.
A lot of people forgo anything but online file storage already, I'd be suprised if the Amiga community doesn't adopt this already themselves or aren't already.
Writing an Amiga program to access a webservice should be easy even from something like AREXX (same kind of idea, AREXX ports just over a network)..
