I could be wrong as well -- unfortunately, a lawsuit is pretty much the
only way to find out for sure which way the license would be interpreted.
A non-commercial mud isn't likely to have the resources to fight a
lawsuit, so it is something to consider.

I wasn't speaking of muds specifically, but of all the code that's being
released under the GPL. BTW, note that not all GNU libraries are released
under the LGPL -- some (such as the readline library) are released under
the regular GPL. Including those libraries does bind you to the GPL.
And if you borrow as much as one line of code from any GPLed program, your
program is bound by the GPL -- so someone who, say, lifts the socket code
from a GPLed program and modifies it for their server is bound by it.
