iMac driving a 1st gen MBA - both with latest Lion and Teleport 1.1.1
I had several problems getting 1.1.1 to run in the first place and had to trash the two com.abyssoft.teleport.plist files in my library preference folder (note, hold down option key when selecting GO menu in Finder in order to get to your user library) and re-install the teleport preference pane on both computers. Now it occasionally crashes and pulls the icon out of the menu bar. Re-launches easily enough. I did have a very odd failure-to-return-cursor event a couple of weeks ago when the iMac stopped accepting any input to wake it from screen-saver. No idea if it was related, but I was using Teleport to work on my laptop when the iMac stopped taking input (bluetooth everything) - system logs didn't offer any clue either - had to hard re-boot.
