I don't discuss the option to use SQLObject.

The thread I've pointed you to (and which is essentially ignored by
turbogears community), discusses essentially the abilities of SQLA and
SQLO.

Can I have at least a direct (=technical) answer to this one?:

"
http://mail.python.org/pipermail/python-list/2006-September/359164.html

"SQLAlchemy implements the Data Mapper pattern, of which the Active
Record pattern (which SQLObject implements) is a subset."

I understand this like this:

SQLAlchemy (DataMapper) can implement SQLObject (Active Record)
SQLObject (Active Record) cannot implement SQLAlchemy (DataMapper) 
"
