I'm building a Spritz-like application but I don't live in the US so the patent doesn't apply. Is there anything else I should be worried about?

They also have a WIPO patent[0], which may or may not affect you, depending on where you are.

Also, since Github is based in US you might want to look elsewhere for project hosting (assuming that it's an open source project).

they don't have a patent. as miket pointed out, it is an patent application and thus unproven and not granted and not enforceable

Sorry, who is miket?
