Sounds like you have two questions. First and most important is hotsync. Check out jpilot, and seach the forums for tips on how to sync over the network. I saw that the other day but don't remember exactly what it was. Anyway for searching, look for jpilot and sync, you should find it.
And secondly, there are some other wallet programs you can try such as STRIP or KeePass.
Hope this helps.
