Hmm. I'm not going to be distributing this, it'll be
an in-house application, for my eyes only. :) The
customers will merely be using the in-house server. So
GPL or not would not be an issue. Robustness,
scaleability and ROI definitely are the issues I'm
interested in.

Again, the licensing issues for AGI or FastAGI using
any Asterisk libraries should not be an issue either.

Okay, so it looks like AGI itself will not be worth
pursuing. That's okay, at least I have a handle on
what I'm doing now. 

So, FastAGI or straight C? I just want something
that's easy to write. FastAGI will have to be wrapped
around Asterisk commands, so I'm anticipating a slight
overhead there, but if it's really not that much
slower, it may be faster to get the IVR code up and
running.

Opinions? Would any of you bother writing an IVR-only
application (like the app_voicemail application) in C?
Why or why not?

Thanks,
Maya
