In this day of web service orchestration and various process- and
workflow-based tools, I'm sure there's something out there that fits
the bill. Just not sure what it'd be. Suggestions?
Well you haven't given us much to go on. Only your comment that you might
want to change a sequence while it is running suggests a large scale. I
am thinking some sort of callback structure, which to me suggests that you
might want to look at POE. POE itself isn't exactly an off-the-shelf
solution but you may find someone has built one for you. Maybe POE::Queue.
