NetCruiser probably doesn't belong on this list, as it's not 100%
WinSock compatible. NetCruiser includes a proprietary stack and
suite of applications included with SLIP accounts from Netcom (a
large Internet service provider), the latest version has added
*some* WinSock compatibility. NetCruiser itself works only with Netcom.
Compatibility Notes: WinSock applications known to have difficulty with
NetCruiser include WinTalk and mIRC.
