Drew, Funny you mention OpenOB. Another one of James Harrison's projects is almost exactly what you are asking for.
Changeling is a profanity delay/dump application that runs through Jack. It'll pass audio from the in to the out. When it receives a command to enter delay, it will play a pre-recorded .wav file and store the input audio into a buffer. The .wav file defines the length of the delay. When it gets to the end of the file it'll pass the delayed audio to the output. When it receives a dump command it dumps the audio in the buffer and instead plays the .wav file audio content, once again putting the input audio from the point at which it received the dump command into the buffer. It doesn't do any audio stretching (the way a commercial delay box would) as it builds up a delay, in that respect it does not offer as "professional" a sound as an expensive commercial delay unit. But if you are on a budget it does work. At one point when testing I had it set up on a Rivendell test box with Rivendell monitoring 3 GPIs on the serial port. When Rivendell saw the GPI trigger it sent the either the "enter delay", "dump", or "exit delay" command to changeling. I hooked those GIP's up to buttons it worked better then I expected. It is open source, available on Github: https://github.com/JamesHarrison/changeling/ I admit that I have not compiled it in a few years. The last time I got it up and running for testing purposes was on Lubuntu 14.04, but I am sure it can be made to work on CentOS or others.
