Ok, once again: The goal of bonobo-conf is not to store everything
as binary data. If you restrict yourself to the basic types used by
GConf the values are even stored in the native GConf format - no
binary data at all ;-)

read/write is not problem, even if you use CORBA_any. The real
problem is if you want to modify values. We have PropertyEditors
for that.

I think "PropertyEditors" as used in bonobo-conf are better and even
easier to use.
