Thank you, all, for the many new suggestions! I know it's been quite some time since I responded (or posted on X Marks, for that matter).

Unfortunately, life has gotten in the way of this little project, and I've had to put it on hold until things settle down a bit. I'm finishing up a master's degree and have been hit with a very heavy work load the past few months. Rest assured that it will be revived and as many of your excellent suggestions as I'm able to include will be included!
