Limit of Listeners & Configuration

[VlatkoM6]

We are considering using SHOUTcast to stream our radio, and we were wondering what the limit of listeners is.

If there is listener limit, is there a possible way of removing the limit?

Also at the moment, we believe we might have around 60.000-70.000 listeners, so does anyone have any tips as to which configuration would best suit us?

Thanks!
