As for the fight scenes, Yuen-Woo Ping choreographed every single one of the movies mentioned, as well as The Matrix. It's not that anything is getting remixed or ripped off in this case, it's just that particular choreographer's style.
Having ancestry of two of the languages helps. To be pedantic though, Yiddish is written in Hebrew, but Hebrew isn't Yiddish. Japanese Kanji are somewhat simplified Chinese characters, (not to be confused with simplified Chinese, but I think Ai is written the same way in Chinese anyway. Kanji just means Han writing.)
Interesting, they were using a Java program to capture Open Sound Control packets, and send them along TCP/IP to Flash. It's be easy enough to use Java's Robot class to turn the first touch event into mouse cursor movement, then any subsequent events can be re-broadcasted to any application that wanted to listen. (You've just set up the Java app as a server. Any other apps would just open a TCP/IP connection to the Java app.)
The point of all this would be to keep compatibility with the OS, with multitouch being a nice add-on for any apps that woud support it.
