The raw data is rsyncable, but you should be using the soap interface
for everything. If there is something that the soap interface doesn't
do that you want to do, you should file a bug against debbugs
requesting a specific feature to be added.
There currently isn't a way to query the version graph using soap, but
in almost all cases, you actually don't want to do that. You should be
using the BTS's own routines to calculate whether a bug is buggy or
not instead of writing your own.

There are cases where a bug exists in multiple different source
packages or different source packages build the same binary package on
different architectures.

It's cleared.

Yes.

No.

Yes, but none of this is important. The BTS handles all of it for you.
