You can use a Wiznet wifi->serial adapter. The NX plugin for Vera supports IP from the reading that I did. No wires.
As for wireless being insecure... it's as secure as you configure it. I guarantee you that WPA2 is going to have stronger encryption than whatever method HAI is using. But, for wifi, there are way more tools out there to break it, and more knowledge about it. Realistically, it's a question of motivation. If you have decent security on your wifi network, no one is gonna spend a ton of time on it. They are more likely to kick down your door and do a smash and grab. Unless you have a vault full of gold or have a price on your head from Mexican drug lords, it's very unlikely that using wifi is going to be your downfall. Plus, the Vera Lite is wired, not wireless. And the lack of wireless is the only difference from the more expensive model.
What do you do about someone using a $35 cellular jammer from dx.com and cutting your phone and internet before kicking down the door? There are risks everywhere.
