Before diving into this code, I have a few things to mention:

• Instead of starting a new thread with correct code, update the existing thread, informing others of the change as an addendum (davorg already considered this node for that reason).
• In the previous node, pope mentioned that POE::Kernel uses Time::HiRes for scheduling, which should probably accomodate your needs.
• In a few places your script has lines to the effect of

  print "\n=====================================================\n";
  [download]

  which can be accomplished with more readability as print "\n", "=" x 55, "\n";, using Perl's repetition operator (x).

Beyond these minor editing considerations, the code looks good (preliminarily, as I said, I haven't dived into it yet, just had a few points to bring up). :)
