Sounds reasonable. Most of the earlier classes in [math] use the ids generated by the JDK utility serialver. I think Eclipse will do that automatically, which is fine by me. I am also OK with Jorg's suggestion or James' (though in the latter case, I would favor 42l - even though I am 42R ;). The important thing is to put something there and change it when a serialization incompatible change is made to the class.
