No. A dynamically created query is not the same thing as an undefineable 
query.

Today a fetch of a hypthotecial 'CELL-VENDOR-NAME-TODAY' could
return  a VQUERY containing:

    ....where RECURRENCE-ID < 20031202T000000Z
         AND RECURRENCE-ID > 20031201T000000Z

Tomorrow a fetch of that same VQUERY could return
one containing:

    ....where RECURRENCE-ID < 20031203T000000Z
         AND RECURRENCE-ID > 20031202T000000Z

How that dynamically stored VQUERY is inserted into your calendar
and dynamically altered depending on the time/TZ is not a CAP issue,
it is an implementaiton issue.

No.  If your cell phone needs 'get-vevents-only-for-today' and you tweak
that VQUERY and change the VEVENT to VJOURNAL's, then you
busted the query yourself, it is not a protocol issue, don't do that.

Cell phones do get me XXX queries now (not using CAP however) and the
cell phone can not change what is returned or tweak the contents of the
query and do not need to download the query each time.
Stored queries allow for cell phones to use CAP.
