Does lNet require LibC or other external libraries?
Depends on platforms and protocols. The base lNet library (lnet.pas) does not require LibC on most platforms (MacOSX/Darwin is the exception). It also depends on FPC since on some platforms the RTL uses LibC. Additional protocols might require LibC and other external libraries tho. Good example is the planned SSL support protocol which will require OpenSSL and LibC (because of openSSL), but it will be made optional. .::TOP::.
