And keeping this up to date...
As far as I can tell, this looks like an end-run around the AWS License
conditions: they might well view the distributed application as a single
"Application". It's also one that they might well notice: you think
they're *that* unlikely to notice which IP addresses are hammering at
their servers?
There's a chance that they'll just track down the IP addresses in
question, find out who owns them, and sue you. There's a rather larger
chance that they'll just block you.
Now you might be prepared to take this risk if you're just
experimenting. But I seriously wouldn't want to build a business that is
solely dependent on the goodwill of Amazon.
I don't know exactly what you're planning, but it sounds a bad idea.
I swear the sigmonster came up with this by itself!
