Longest common substring / subsequence

[Terry Judd]

I'm find myself getting deeper into the murky/difficult/fascinating 
area of sequence analysis (of behavioural data captured within 
educational technology environments) and was wondering whether anyone 
had succeeded in implementing routines for finding the longest common 
substrings or subsequence in a pair (or more) of strings? If so would 
they be prepared to share them?

Failing that, I've found some pseudocode for dynamic programming 
solutions to these two problems that may be doable in Rev (???) at...
http://www.ics.uci.edu/~dan/class/161/notes/6/Dynamic.html

Thoughts?
