yes, but it must not be done all at once. If there are (new) requests for
certain classes to implement Serializable, one could instaed implement
Transportable. Besides the documentation provided by interface Transportable,
it should be discussed in a general policy document of AC Math with reference
to the discussion in this thread. There is a possible conflict when AC Math
later decides on a long term serialization mechanism. An additional interface,
say "Storable", could then interfere with Transportable. But as "Storable"
could at that time mean something different to Java Serializable it is open
how to combine the two.
