I'm developing a quite popular mobile application which needs to download some amount of data at first run (then check availability of new data periodically). Currently I'm using shared hosting at Dreamhost and I'm very satisfied, but when downtime occurs, fresh users are screwed, app won't work without initial package.

I can buy secondary hosting and embed source switching logic inside app, but it raises complexity of network part. Instead, I was thinking about some kind of distributed hosting, where data are available from multiple locations.

I need only hosting of files. Are such services available for cheap? Is the Amazon S3 the right direction or should I look for something else? What are disadvantages?

Let's assume we have two Windows XP computers with identical hardware configuration, including GPRS modem connected to COM1 serial port. On the first PC we add new modem device, set up gprs connection on this port in "Network connections" folder. How avoid clicking the same procedure on second computer?

Detailed questions:

1. Where are the entries from "Network connections" stored? File, registry? Is there a possibility to clone such entry between PCs?
2. Question as above but regarding modem entry in device manager - can it be exported from one pc and imported on second?

What is the button on power supply of the Dell Optiplex 760 workstation for? There is a small button near LED power indicatior - seems to do nothing when pressed.

I'd like to provide LAN users access to set of useful and popular applications (like Acrobat, Firefox, Foobar, putty) but there is one problem - such software is released every few weeks or even often. What is best method of automatically downloading most current versions? Every download page looks differently and only a few has permanent "xyz-current" links.

Disclaimer: I know newer not always means better but in many cases (like browsers) it at least mean safer.
