There is a new release (v1.0.25) of the increasingly inaccurately named NETBOOT65 by jonnosan, which now includes:

• NetBoot – the original „boot a c64 via tftp“ cartridge image
• KipperKart – net booting, SID player, web application server and more
• KipperGo – a gopher and simple telnet (vt100 and petscii) cartridge image
• KipperTerm – telnet client (vt100 and petscii) plus XMODEM support

See http://netboot65.sourceforge.net/ for more.
