WARNING: pssh is substantially UNTESTED and probably INSECURE. 
Do not use it for security-critical applications.


COMPATIBILITY

Requires:
Palm OS 5.x.
an ARM-compatible CPU
a network connection

pssh has only been tested on a Tungsten C. It may not work on other devices.
pssh is EVEN MORE INSECURE on devices other than the Tungsten C because 
it does not use device-specific random number sources. Contact the 
author (gparker-pssh@sealiesoftware.com) if you are willing to test some code.
