Firewall-like software for Clie

[Burns]

I'm looking for a firewall type of software that will block/allow only certain websites on the Clie. Is this available?

If not, I'm looking into writing this myself. This will be my first endeavor into palm programming, although I've been programming as a profession for 4 years. Can anyone give me insight as to how I might intercept the connection calls sent to the wifi card? Also, if someone would like to join me in this project, let me know.

Are you looking for filtering software, like to block websites, Or do you want to protect the Clie from hackers and stuff?

The purpose would be filtering. What would really be nice is one with password protection separate from the palm lock feature.
