comment In what way is XXTEA really vulnerable?
I would tend to look at it from the other direction: do you have a specific reason to use something other than AES? If not, that's an obvious and safe choice (with many freely-available implementations).

Google for "traffic analysis" for some ideas about how the traffic can be used without decryption, but only if you can distinguish real traffic from random trash.
