Following LTC Timecode and/or sending LTC to external servers.

Hmm... Adobe have spent an extraordinary amount of time persuading Audition and Premiere to play nicely together, but unfortunately their idea of 'nicely' doesn't involve remote synchronising, as such - it's all about a round trip, and nothing else. The closest Audition got to being able to synchronise to any external source was back in version 3, which had an implementation of Rewire in it, although this didn't really work that well.

It's a shame, but I don't think that Adobe actually want Audition to be able to do things like this, because potentially it cuts down on their revenue stream, if people only sign up for one product. And that, also unfortunately, is what drives Adobe along - not actually doing what relatively small customers want or need, but just the things the big guys want. Because they're the ones with the purchasing power, and who are effectively paying Adobe's wages bill. If you look back through all of the ideas that have been submitted to them, well over 95% have been either ignored completely, or put 'on the back burner' (which often goes out...).

Adobe's get-out clause here is that they've released an SDK, which means that potentially, people can write plugins for Audition, that could add additional functionality. Very few have appeared, because it's really not that easy to do; you need to be a stubborn, dedicated programmer before you'll get anything like a result with it. And I have no idea as to whether you could get it to sync to external video.
