Just wanted to chime in and say I'd love to see VSL implement the Waves solution, with temporary licenses in need of reactivation every 90 days or so. That would sure make me sleep better. I'm really paranoid about loosing my dongles.
I love the Waves TLC program.
HOWEVER, before VSL does a similar solution, the engineers and designers must make it SO EASY that a caveman can do it (sorry, a reference to a US insurance company marketing slogan that has jumped the shark). Right now, getting auths and manually copy/pasting to the eLicensor is quite a process -- can't imagine doing this every 90 days for a dozen or more auths on multiple dongles. Waves consolidates auths into "bundles" so I only have 2 auths to deal with. Just sharing.
