Sealie Software is developing pssh, an OpenSource SSH2 client for Palm OS 5. This is an important application for Linux system administrators on-the-move. Pssh is meant for fast Palm PDAs with high resolution screens, like the palmOne Tungsten C.
Pssh is not currently for devices like the palmOne Treo 600 (lower resolution screen) or the palmOne Tungsten W (slower processor). If you need support for those devices or for SSH1, the developer recommends TuSSH or Top Gun ssh. [ via MobileWhack ]
