Xmms_remote allows you to control XMMS using a palm pda via the hotsync cable.
This program is buggy, unreliable, undocumented, and prone to spontaneous combustion. It will probably remain this way for a long time to come, as I do not intend to polish it up. Note that from version 3 of xmms_remote onwards, it will block all power-off events and blank the screen instead.
This software consists of 2 programs, one running on your PC (xmms-pilotremote), and the other on your palm PDA (xmms_remote).
