I've updated mine to use a cache.
Check out `table.php' in
http://servb.ath.cx:3445/~luke/1024/frcfms/cached/
The cache is out of-date/missing entries, because I was testing it on my computer, which didn't have constant internet, and now shell_exec is disabled on the server for security purposes, and it is needed to update the cache. Anyway, if it were enabled, it would update every minute on the minute.
