Hi,
In general like the proposed solution better than the current, but an 
extension which allows the distribution to see the aliases of the servers 
would be neat as well. This certainly would solve the issue of placing 
datafiles.

>Julian, how would this stuff fit in with your migration/hints stuff?
I use the actual server aliases as targets to ensure proper placing of the 
datafiles in an environment with miscellaneous sets of dataservers.
In my opinion a decoupled system for file creation and the distribution 
parameters seems important to allow later relocation of datafiles to another 
data servers without conflicting with the distribution parameters. Therefore, 
the location of the datafiles should be transparent for the distribution and 
never be set in the distribution parameters itself. Another reason not to 
store this info in the distribution parameters is that once the target 
dataservers are determined this information 
simply becomes obsolete.
