considering the cost of small quantity for these displays, why not
just use a small pda with a serial port as a terminal?  a palmos 
device could function as a terminal with it's onscreen keyboard.

i've been thinking of using my palmV in this way recently.  

or for kb input, an older palmtop capable of 80x25, such as an hp 100/200lx 
or a fujitsu poqetpc should work well for these applications and would
have smaller footprints.  I know the matrix orbital 40x4 lcd panel is 
thicker and longer than my hp200lx when it's folded up.  

I don't know if the new palm zire has a serial port, but it may be more
cost and space effective than an lcd panel and keyboard and everything 
all hacked together. plus they'd be usuable in a detached mode as well.
