Cd emulation

I have an application, that makes a cd, and then burns it, it doesn’t allow me to save it as a iso image, but I can’t burn it(no cd burner) so how would I make it burn to a iso image. Kinda like cd emulation except I want to write to the cd as well.

oh yea the application is for mac.

I have another solution in my head, I run ubuntu on a computer that has a cd burner, is there any way I can mount the cd-burner device over to my mac over a network and then use it to burn a cd??
