Oh.. you mean services .. not stacks.  I read that to mean like
Netware or Appletalk support. I will take a shot at this one. :)

   + TFTP read client (Eric Norum has said he is close to write
capability).
   + no FTP client AFAIK

   + some people have setup custom telnet servers but no clients AFAIK.

  Yes.  See libnetworking/rtems_servers.

  Yes.  There has been some discussion of bootp versus pure dhcp and
  a post recently on the mail list.

  Yes.  A port of ucsd-snmp is in contrib.

  Yes.  GoAhead in libnetworking/rtems_webserver

  These I do not know about.  Help!!!

  RTEMS replies to pings.

  THe ones I answered yes on are either in RTEMS source already and
  there is no license or in contrib and need no license. 

  The GoAhead webserver has a unique license you might want to look at.

  Multiple people have ported various pieces.  It tends to be a fairly
  straightforward task these days to move BSD code to RTEMS if you
  follow the pattern the existing network code does.  If you port
  an add-on package like ucsd-snmp, then it is simply application code
  and ports based on its porting layer.

  I believe the networking guide explains the architecture of the
network
  stack port.
