So the basic premise is that you want to use an audio application, but
without audio hardware?

In order to do something like that, you'd need something that ALSA can
talk to.  This could be a compatible voice/data/fax modem that ALSA
can treat as a sound card, or a USB headset (which presents as a sound
device if done correctly) such that you can use ALSA with that.  Other
than that, you'd have to write (or find, if one is already written)
some sort of a program that could use the network as a bus for the
audio transit, and written in such a way as to implement the ALSA API
so that normal sound applications can use it.

(I am assuming that the program of which you speak is written to the
ALSA API, but if it is not, then substitute PulseAudio or OSS for ALSA
and it is the same basic idea).
