Sorry, this is a stupid assumption. The ZODB stores Python pickles and not 
any kind of source. Means when you load objects from the ZODB the 
corresponding classes in terms of sources must be present to unpickle the 
data. This means for you: every ZEO client need the full source. This is 
not an implementation issue but just an issue of your ZEO installation: 
when you load data from the ZODB then the sources must be present, 
otherwise your objects will be broken. Point.
