I'll have to try the Growl thing then (whoops, no that won't help in the event of a locked up system, which is my sole interest here.) I installed NotifymyAndroid and registered but it comes with no instructions, and the website (netchup.com) is gone. Lots of reviewers complaining it doesn't work or stopped working, though some (as of their review) say it was still working for them.

Update: Found the new website; API stuff looks way over my head. Last time I programmed was 25 years ago in FORTRAN, unless you want to count doing HTML pages in Notepad back in the mid-late 90's...
