text: Not too sure about Airport time out issues either.  For VNC, I use that a lot between my Macs and PCs.   On the Mac (10.4 preferred), you can either turn on Apple's own Apple Remote Desktop (System Pref -> Sharing, choose Apple Remote Desktop.  Click on Access privileges, grant yourself full access + check on the VNC viewers ... and set a password)  OR OSXVNC (free ... the new version is called Vine Server)  To install this guy, download it from their site (you can do a Yahoo search on osxvnc).  Double click the DMG file, drag and drop the content (Vine Server) onto your Application folder.  To configure it, launch the app, set a password and you're set to go!  Client for VNC, I would go with "Chick of the VNC".  Do the same get process as osxvnc, search for it on Yahoo, get the DMG, drag to Application folder and launch!  It can memorize your controlled machines, which is cool.  It doesn't care if the destination is Mac or Win as long as you have the right IP address and password.  Right clicking on a VNC Win machine can be a pain if you don't have dual button mouse.  You have to hold down control + shift + click to do right click on the PC you're controlling.\n\nOn Windows, I use UltraVNC (also free).  It comes with both server and clients.  The server is as easy to setup as OSXVNC (when you launch it, it stays on your tray, double click it to give it a password)  Then, with the client, supply the IP address of the Mac or Win you want to control + password.  There's also WinVNC -- the downside is that WinVNC will auto start itself, you have to manually shut it down if you don't want it running all the time.  There are 64 bit versions of the VNC for UltraVNC -- do a quick yahoo search of "ultravnc 64"
