No, the problem is exactly choosing the address: modules overlap with
each other, and manually calculating baseaddresses often doesn't
work. Alex proposed to automate this process and do a
baseaddress.rbuild file generator.
There are not many dlls with baseaddress missing, and if it's
missing, it should be added to those (in trunk).

Not really, in most cases (might be with a few exceptions), it's not
possible to use exactly Windows' base address (because size of our
modules and windows modules often differs). The problem is to
distribute the dlls in the memory address space so that they don't
As for baseaddress in xml form - baseaddress is a module's property,
it's not a standalone object which is part of the module. I don't see
why it should be given a standalone tag (maybe I'm missing something).
