William is concerned about speed of processing. I know 160,000+ plus entries in a dictionary is considerable, but even primitive steno software in the 80s was able to handle ~60,000 without blarfing. There must be a way to optimize it. Obviously guessing algorithms are trickier and will take still more speed, but we're not talking fancy graphics here. I will have to think of some way to obtain the numbers; my guess is modern computers won't balk at the sort of simple text searching functions we need, even if they're implemented in a high level language like Python. I just need to confirm that guess.
