With Back to My Mac and iChat screen sharing, remote control options feature heavily on the Sparta List of Leopard features. Now, the remote control tool LogMeIn Free, in beta for the Mac since June, has reached release status. With the free client you can initiate or accept remote control sessions, cross-platform and through most firewalls. It's great for family support or switcher hand-holding. The 5.5 MB client can be downloaded now, and you can use it once you register with LogMeIn.
LogMeIn has a heavy following among IT pros, who may subscribe to the industrial-strength IT Reach version of the product for additional features. Having a Mac client as a full peer helps remind those systems managers that there's a different-thinkin' crowd out there in the market.
