This shouldn't be a problem. Other distros with more real world
experience than maemo cope with this pretty well. For instance, Debian
unstable has nowadays two parallel installable versions of libsoup.
Objects link against either of them depending on their needs. There
should never be the case when someone is linking against the two. Not
even if dinamically loadable modules are in place.

In our case, Nokia applications and libraries link against what's now
shipped by Nokia. That's not going to change. If there is a parallel
installable version of hildon, those interested on using it link against
it and so should all the modules that they want to load in runtime or
whatever.

And as far as I know, maemo-launcher only boosts the GTK+ library, but I
might be wrong.
