Just to display the HF radio's frequency, band, and mode, etc.  The users just QSY's his radio to he SkyCOmmand frequency, and monitors for 1 minute and he will get
an update packet showing what the HF rig is tuned to.

Maybe, I was thiking of just using the HF symbol.

Yes, I can enter a FREQ and APRSdos will send the correct SkyCommand packet to cause it to happen.

True, but why write a whole new application just to display a frequency and mode and to send just a single FREQ comand?
when you already have it running and might just want to QSY for a minute to see what the HF is listening to.

Yes, if they transmit AX.25 in UI packets, thn it makes sense to monitor them in APRS. But if they have nothing to do with AX.25 then there is no reason to have them in APRS.
SkyCommand comunicates just like APRS, by using UI packets for command and display of data. 

This is EXACTLY what APRS was desgned for years ago, to display to the user EVERYTHIGN going on in ham radio around him that wasavaialbe on AX.25 UI packets.
