Amy Rinehart sent me this link to a very helpful chart of remote-desktop solutions currently on the market, which platforms they support, what protocol they use, how strong their encryption is, etc. Remote screen control has become a major interest not just of nerds, but increasingly of iPad and other mobile users in general. After trying Copilot from Fog Creek for a while, I myself have landed on GoToAssist as an affordable and easy-to-implement tool for servicing clients (as of writing, this link from twit.tv gets you a discount; thanks, Leo!). I'm anxious for Citrix to release an iPad app for GTA.
