I have a general question, coming off of the above posting.

How portable are analyses in these different systems?  Obviously if an 
analysis uses some feature that exists in one system but not the other, 
you're out of luck.  But if you stick to what's *conceptually* common, 
how easy would it be to take a grammar written in one *formalism* and 
port it to the other?

Putting it differently, twenty or thirty years from now, when neither 
system runs on whatever computers and OSs we're using then, will you 
still be able to run one of these systems?

(Apologies if this is answered in Nurit Melnik's article; our 
institution doesn't subscribe to Research on Language and Computation, 
and Springer wants its usual outrageous dollar a page for a PDF.)
