Licensing and Remote Desktop Services in 5.3 vs 6.1

Our office recently made the switch from Arbortext 5.3 to 6.1.

We have node-locked licenses for all our new 6.1 machines and today have just come to realize that in this new version, users cannot work remotely via a remote terminal connection. After contacting PTC support, the only way a user can remtoely use Arbortext is with a floating (more expensive) license type.

In 5.3, node-locked or individual licenses worked fine over a remote connection and now we might get burned by this licensing change. Is there no other alternative than to just buy the more expensive floating license?? I'm just posting here to maybe see how others dealt with this change as we can't have been the only ones burned by this.
