I use Gnosis Utils for a similar purpose. The API is similar to pickle, but if you need to control the details of the serialization (which fields get serialized and how), then that is quite different. Gnosis has a concept called "mutators" for this.

Is there some easy solution of this problem?

yes, the receiving application needs to have the same mapper() setup as the sender. If you use the "declarative" extension to setup your classes, this task is made easier.

And additional question - is there some "simple" way how to "convert" (marshal, serialize) reflected sqlalchemy class to "human- readable" XML?

we dont have an XML serializer but there might be something on Pypi for that.
