I'm just making an assumption there, maybe they do clobber each other.

If I understand right this is how databases work (Mysql, m$ SQL server, etc) 
the sql server reads in the database file and then handles all the record 
locking/conflicts.  I'm not much of a programmer but I think doing similar 
would work the only difference would be it would respond to DCOP instead of a 
network port (could make it listen on a network port as well, share your 
calendar).  Basically make the libkcal start up when any app calls it, then 
it reads the ical file and does the communicating with the applications.  
Each application would make the dcop calls and those would trigger the 
loading of the libkcal "service"  A file open command would be passed trough 
the libkcal service instead of the app reading the calendar file.
