assuming that does what it sounds like it does (I haven't read the source), that's a great idea!

my phone can do AIM - so perhaps I can use this as a replacement to my e-mail reminders... although likely pretty much similar.
I had it setup for awhile that the code would look at a time table and based on where I likely was at that time, would send out an e-mail of reminders - so it might end up at a local account, my work account, or to my phone.
I stopped using it because I don't tend to move around so much anymore and therefore it is easy enough to just use my work pc much of the time... that and I kind of like being removed a bit from it all time to time.
