Thanks to all who replied!
Here is the skinny:
First off, get the linein plugin by whateverthehellshisname deGronde:
Read his FAQ. Basically what his plug-in does is transefer whatever is being recording by the soundcard to WinAmp as an input stream. Which means, whatever you can configure as a recording source, can become an input stream. Which is sweet!
BTW, I would love to know where all the shoutcast experts are in this so-called forum. I have posted a number of questions, never to find them answered, even as I myself have answered a number of newbie questions. Is everyone afraid of giving hints to the newcomers, for fear that their station's listeneres may drop from 12 to 10? I have tried to use these forums as a first line of defense, and have found them useless but for the entertainment value they offer in the means of meaningless egotistical catifights.
Nice work, to those who've earned it.
