MCCP needs to be done very low down, even the telnet negotations come after
MCCP decompression.  What Will refers to as 'markup languages' are what
most mud 'protocols' are, and can be done with a text filter. Check out
ANSIStream in sandbox/leantin/ansi.py as an example of a filtering 'protocol'
handler.  It takes text in and returns marked up (color, text) pairs while
keeping a little state about the current color and unfinished sequences.
An MXP stream object could similarly just filter the text before it hits
the UI window and keep some internal state (like room exits).  So this
is easy to do in the mud_filter_hook like Will mentioned.

In regards to MIP/Portal, the cryosphere link[1] sums up my feelings nicely.
 "This closed spec has an obnoxious licence that forbids technical commentary of it.
  Only one client (portal) supports it"

Here is some non-technical commentary.  MIP is terrible, the protocol isn't
any more useful that a good set of regexps and it is designed so they can sue 
anyone that tries to implement it without giving them money.  They no longer
charge muds for implementing it because they would like to sell more clients.
And still no one cares enough to implement it.
