In 2001 I did implement some Real Time LPC on C6711 DSP.Try searching for
Jeff Burke and LPC. I got some stuff from this source in 2001 for one of
my projects. In UCLA there was a speech based ee course where Proff.Ingrid
had some Real-Time LPC exercises. I found them quite useful at that
time.BUt am not sure if those web pages are still alive.

Hi,

Numerical Recipes in C has a section on LPC
with some code examples (not real time, but
demonstrative and adaptable).

The link below will take you to the relevant
section PDF file where the book is maintained
online by the Cornell library.

http://www.library.cornell.edu/nr/bookcpdf/c13-6.pdf

Hope it helps,

Dave.

This is the one I was thinking of,

http://www.amazon.com/exec/obidos/tg/detail/-/0137890095/qid=1121891126/sr=1-2/ref=sr_1_2/104-6019770-9339121?v=glance&s=books

I believe this is the most recent one.

I can't help with code, but I do like your ideas for the lab.
You might just find something useful in the collection of signal
processing exercises for matlab, (just ignore the fact that the
exercises were written for matlab 5, it doesn't matter)

http://www.amazon.com/exec/obidos/tg/detail/-/0132198258/qid=1121887559/sr=1-5/ref=sr_1_5/104-6019770-9339121?v=glance&s=books

If you are capable of coding some of these things yourself, first
in matlab, then in C, you might get what you want. You may even
be able to make matlab-based exercises, which may be a bit more
convenient. (I am assuming that you, like most universities, have
lots of matlab lisences and not quite as many DSP boards.)

Dear Sirs
I am a teaching assistant at MSU, and have volunteered to create new
labs for the ECE Senior Design class. I would like to make the intial
project a real-time LPC encoder/decoder. I would have the students play
with the pitch value, so they would learn about LPC and also get
excited about DSP.
We currently are using the TMS C6711 DSP board from TI. I've searched
high and low, and can not find any C code at all, that implements LPC
anything. I only know the most basic information about LPC, so I am
rather wary of approaching this project. I need something free and
simple, so I can create this "playtime" lab.

Any help would be greatly appreciated!
Thank you. 
Kyle
