You may notice a slight delay when you move windows around, but you won't have any trouble working with remote documents or using a Web browser on the host PC. Sound from the remote PC comes through fine, too. But full-screen video or other graphics-intensive tasks will be choppy at best.

To copy files to and from the host, you can drag and drop or use a separate file transfer and synchronization tool. And a simple slider allows for easily adjusting the display to favor either connection speed or appearance.

GoToMyPC uses encryption for all connections, and it allows you to print out a list of one-time passwords for each host. If you want to give other people access to your host PC, you can send a temporary e-mail invitation to share your desktop with a guest. The invitation automatically expires in your choice of 1 to 3 hours, or you can cancel it manually.

Though GoToMyPC isn't cheap, you can give it a whirl with a free 30-day trial for one PC. For businesses that want to provide the service for up to 50 employees, a Pro version offers central administration and billing. A Corporate version allows for more than 50 users.

LOGMEIN PRO

LogMeIn Pro's remote-desktop service directly competes with GoToMyPC, and the two offerings are similar in most respects. But LogMeIn Pro costs a fair bit less, with a monthly fee for one PC of $13. Each additional computer (up to ten) runs an additional $10, with discounts for each PC beyond ten. The service also provides a free trial for 30 days (or for 120 minutes of usage, whichever comes first). A no-cost, feature-limited version of the service, called LogMeIn Free, lacks options such as sound and remote printing.

You can install LogMeIn Pro on a PC running Windows Vista, XP, or 2000, or Windows Server 2003, 98, or Me. Macs with Tiger or Leopard can run LogMeIn Free, but not the Pro version. You can take remote control of a configured PC or Mac from almost any Windows, Mac, or Linux PC, or Pocket PC device.

Similar to the process with GoToMyPC, you start by logging in at logmein.com and choosing from a list of connected computers. But whereas GoToMyPC then launches a Java client outside the browser, LogMeIn runs within the browser, so first you'll need to install an ActiveX control for Internet Explorer or a plug-in for Firefox. You can skip the plug-in and use a less attractive Java interface instead, if you wish (either option allows a full-screen view).
