Oops yes, I missed the 'append=TRUE' flag. That's a good idea. Last time I did something similar to this I used a relational database for saving. I created a table of all the i,j pairs with columns i,j,distance and 'ok'. 'ok' was set to False initially. Then I'd query the db for a row with 'ok=False', and go about getting the distance. If I got a good distance back I set 'ok=True' and never bothered getting that again. This was in Python with SQLite as the database engine, but you can do something similar in R. With a distributed database you could easily split the queries between as many servers as you can get your hands on.
