Honestly I haven't spent that much time using LMI, but I've always been thrilled with TV. Yes you have to download an exe but I usually e-mail the D/L link rather than attach the file. To run once, it's a live run, no installation. If it's a machine that I have to access frequently you can install it as a background service that opens with windows so I don't even need the person to give me the code anymore, I have a preset admin password.
