How about a binary file with locking?  Would be useful to have a locking
library in kde anyway, seeing as a lot of libraries could use this feature to
avoid data duplication.

The trick is getting the locking to work across all supported systems and
NFS.  Once that is done, the first program to start gets the lock, parses the
config file, creates the binary version, releases the lock.  Everyone else
can just read the binary file quickly (since they use the same library, they
have the same data structures :-)  ).
