From AIM Productions:
Syncing content to your Pocket PC has never been easier and cheaper! Automatically sync ANY type of content in ANY format from ANY internet server to ANY Pocket PC! MagicSync Lite is a fully-automised solution for syncing content of any nature to your Pocket PC on a regular base. Once installed on your desktop PC (no installation on Pocket PC necessary), MagicSync will pop up each time you put your Pocket PC in its cradle and will fully automatically check a predefined webserver for a file list. Any new or updated files will be downloaded straight to a custom directory on your Pocket PC. Everything happens automatically and completely transparant, even behind firewalls and through proxies.
