One of the reasons behind the creation of the RowSets specification was this
very feature of Connection objects , viz. that they cant be serialized. And
it does make some sense , since a connection is a logical binding between
two specific entities.
I am sure that you could always design a workaround to your problem with a
lil' RowSet help.
