Hi,

as far as I know, the owner of a given piece of software still has all 
rights even if he publishes his software under a given license. What 
I am after is, if a given piece of code is published under the BSD 
licence the publisher should still have the right to publish the same 
piece of code under e.g. the GPL and vice versa. (At least as long 
as one licence does not exclude the right to publish under other 
licences)

Can someone with more experience on that matter confirm this 
please?
