This means that it is safer for senior managers in a company to communicate using private ADSL Internet connections to their desktops rather than using a corporate LAN.
Afraid not. The timing attack is an attack on the SSL server. So as long as the SSL server is accessible at all, the attack can be mounted. And once the private key is recovered, then you no longer need LAN access.
While the timing attack is the attack against the SSL server, it is my reading of the paper that the attacks' success largely depends on ability to tightly control the time it takes to communicate with a service using SSL. Currently, such control is rather difficult to achive on links other than ethernet. Quite so. What I meant here was that as long as Ethernet access is provided to the server at all, having your own traffic sent over a non-Ethernet link doesn't protect you.
