we have a bunch of folks who are very opposed to anything "global" at
all. SA 0.2 abstracts the Engine away from the Table by using a
MetaData object, which is just a collection of Table objects, and may
or may not be connected to an Engine. an available subclass of
MetaData is DynamicMetaData which just has a threadlocal "engine"
variable, and is the effective replacement for the ProxyEngine. so
it would be definitely nice for ActiveMapper to allow specification
of a MetaData object, even though there is still as usual a "global"
DynamicMetaData accessible via global_connect().

What is wrong with __engine__ module variable?
If it is possible to still connect to different database per
python module
then I guess I'm OK with global_connect. Just give me a recipe how to
connect to different database in each module and I'll be happy.
I dislike having ActiveMapper have its own ProxyEngine when
SQLAlchemy has a globally defined ProxyEngine called the "default
engine" that can be accessed as: sqlalchemy.schema.default_engine.
You should be able to get the functionality you need simply by
creating your engines and doing the appropriate dance with the
default ProxyEngine in your modules.
