It would be great -- if it worked. Paul Holbrook notes in his blog:
Mac OS 10.5 has a VNC server built in to allow remote access back to your Mac. Many sites have claimed that standard VNC clients will work with Mac OS VNC.Mr. Holbrook reports some success with Windows on the LAN, but nothing from a remote client. I haven't had any luck connecting over the LAN using the Linux command line client, xvncviewer. I get the following error:
main: End of streamIt's not the firewall, since the superb Vine Server 3.0 for Mac OS X 10.4 & 10.5 worked like a champ: I installed it on my Leopard machine, and then connected immediately with xvncviewer over the LAN. I'll let you know if I get the remote connection going.
