Is there any tool that utilizes rtmpdump to allow multiple videos to be downloaded whether at once or in order?

Not tested, but with Bash you should be able to do this

#!/bin/sh
# Concurrent downloading!
rtmpdump -r URL1 -o vid1.flv &
rtmpdump -r URL2 -o vid2.flv &
rtmpdump -r URL3 -o vid3.flv

# Sequential downloading!
rtmpdump -r URL1 -o vid1.flv
rtmpdump -r URL2 -o vid2.flv
rtmpdump -r URL3 -o vid3.flv
