>Seeing as how the delayTime is an AudioParam node, why not just expose some of the attributes of that node to allow developers to tweak the maxValue, minValue, defaultValue, etc?

I guess the problem here is not to expose the interface, but that what kind of interface should be exposed. You definitely hope it can be done as xx.setMaxDelay() than xx.getdelayParam().setmaxValue(), (and what's meaning of setMinValue() here ;)  Also for later case, you need to make it available for every node to make it an universal approaching.

About the upper limit, I guess there had to be some limits, since buffer say more than 1000s data for a bit-rate around 100-200KB/s might be a good way to kill your memory quickly.
I also see some potential uses for maybe tens of seconds delay to give a chance for real time analysis and prepare some visual effect which need an animation and need to be sync upon the rhythm. While I am curious on what kind of usage might need more than hundreds or thousands of seconds delay? ;)
