I am not sure that approach is realistic. I mean, if you say it must be 
optional and not required, then there must be an existing alternative. 
And that alternative must be not LGPL. If there is such a toolkit, then 
why not go with that right away? The project has to manage its resources 

Also I am not fully understanding the problem I guess. It can't be 
source problem, as long as the LGPL source is not included. compiling 
against an public available LGPL source for dynamic linking itself can 
also not be the problem. I do see a problem in the distribution of the 
dynamic linked library. But if you do not distribute it and expect the 
system to have it, then it should be no deal breaker. I mean otherwise 
you could not compile against glibc or example.

And thinking this further... assuming QT is optional somehow. Why is it 
then suddenly ok to distribute it in the convenience binary? Imho it is 
not, even then.

Legal makes a difference for language/platform lgpl code. But why I 
don't understand. A ticket for LEGAL in that matter would be good, but I 
think that should be done by a member of the corinthia project. As I 
know legal, it will depend on the special case and there won't be a 
general answer.
