One workflow issue I've encountered recently in testing these programs has to do with spacing.
I've had a number of clients who have very specific ideas about timing and crossfades, and also the timing when doing a re-release where the resultant master's timing must be identical to the original release.
In these cases they've sent small sound clips of the intermediary timing, which I line up in my DAW until they are absolutely sample accurate, then export the entire side (or full album) as a contiguous file and then insert the track markers.
None of the programs I've tried seem to allow the overlay of a second channel of audio, which is what I would need to do this as an out-of-DAW experience.
My current method is working fine but I wanted to ask how any of you handle this issue with these programs (obviously I know that full on DAWs like Sonic Solutions, etc allow multiple tracks, etc).
