Perl scripts

Do u think Dreamhost would let me run a Perl script 24/7. The script basiclly recieves a game servers log file and then sorts the events of the log into a mysql database?

Also one more thing. If i buy a package now is it easy to upgrade to a better one later? or would I have to buy a whole new account.?

Upgrading is simple, as are most accounting matters with Dreamhost.

If you go for the discount by paying for a whole year in advance, DH will prorate how much credit you have left and apply to new package.
