I'd vote for making Proof SExpression'able (and consequently implement
java.io.Serializable). Just seems sensible and thinking about it... I
hit the same problem (but never got round to raising the issue) about a

Guess we should be adding things like this to the 'Future Work' section
of the site (so we don't forget them) - until we get an issue tracking
application going...
