Broadband over CDMA networks ala EVDO sounds like a really cool
technology but I'm wondering about the security implications. I did a
google search but didn't find any definitive answers.

Does EVDO have robust encryption built into the protocol or would I be
broadcasting in the clear? How, other than a VPN/Proxy setup, could I
secure such a connection?

Thanks!
