Yeah, treating your clock and calendar like power launch icons would be nice.

I know about the status bar alarm clock, but that only shows if you already have an outstanding alarm present and that immediately goes away once it's triggered.

For the calendar, there's Seqretary, GPE Calendar, mCalendar, Den in the USA made mention to something of a Google Calendar app (?) that he installed somehow (I should look that up), I also have a really great Greasemonkey script to show the Google Calendar webpage in full screen mode without any menus and junk, it's actually very nice (Kozzi helped me with the script for it).

Anyway, being able to have either some command line or option as to what your calendar shortcuts to would be good if you feel the same way about it.

But yeah, I thought that would better integrate your two apps with the desktop environment using the least amount of additional coding needed for them.

Cheers!
