Launch only Ultrapeer mode in System Tray

[ElllisD]

I use LW 405 Pro, on XP Home with 2 user accounts. I've noticed that LW remembers it's configuration seperately between users, and although the other user on the PC (my mom) doesn't use LW at all, I'm trying to get LW to run only in Ultrapeer mode. As invisibly as possible. I've set connection to auto, Ultrapeer on, the download limit to 0, and the upload slots to 0, so as to minimize the effect on bandwidth & CPU, set LW in startup, and the shortcut properties are set to Launch Minimized, but it still starts as usual with the splash screen first, then the main window.
Optimally, I'd like to eliminate the splash screen entirely, but I can live w/ it there for a sec, but mom's not gonna stand for having to close the window each time she logs on. As for the system tray icon, I can hide that via Windows. How can I get LW to launch into the System Tray?
I'm also wondering if there's a way to launch LW on my side of Windows when she logs onto her side, so it's invisible to her side. But then I guess if she restarts, there's a problem. It's probably impossible, anyway.
