Having add-ons in dynamic libraries is currently not supported but i'm
working on it - shouldn't be difficult to implement. The only question is
about the method of registering those add-ons: we may use a section in the
configuration file or we may list all .so files in some directory - i
suggest $KDEDIR/share/apps/konq-embed/addons/ - or we may allow both
methods.

Currently -export-dynamic is enabled in konq-embed/src/Makefile.am -
removing it (like I do) reduces the executable size by about 650kb (i386).
That option should be conditionally added anyway since it's required only
when KJS is loaded dynamically or when dynamic add-ons - like yours - are
used.

That only works so easy on Linux and other ELF systems. On Windows symbols
can be exported only from libraries - not executables - so Konq/E must be
broken into one or more libraries and a (small) main program.
