The method of claim 4, further comprising: using a shortest path graph search technique between a start and end of the missing portion of the event message stream to generate the optimized version of the missing portion of the event message stream. 7. The method of claim 6, wherein the event interpretation rule is in replacement form such that fields in the first state are replaced by parameters of the incoming event messages of the event message stream. 8. The method of claim 7, wherein said using a shortest path graph search technique includes: extending the event interpretation rule in replacement form to unconstrained replacement form; and using the extended, unconstrained replacement form rule as an estimator function in the shortest path graph search technique. 9. The method of claim 7, wherein the event interpretation rule is in unconstrained replacement form, and wherein said using a shortest path graph search technique includes: extending the event interpretation rule in unconstrained replacement form to uniform unconstrained replacement form; and using the extended, uniform unconstrained replacement form rule as an estimator function in the shortest path graph search technique. 10. The method of claim 7, wherein the event interpretation rule is in uniform unconstrained replacement form, and wherein said using a shortest path graph search technique includes: using the uniform unconstrained replacement form rule as an estimator function in the shortest path graph search technique. 11. The method of claim 1, further comprising: a plurality of subscriber nodes, including the subscriber node, each specifying a respective event interpretation rule to map a respective event message stream into a respective first state; and a sequencer node, or a plurality of sequencer nodes, receiving the respective event message streams, and using each respective event interpretation rule to update a respective second state corresponding to a subscriber node as a function of incoming event messages of the corresponding event message stream, in preparation for delivering respective, optimized versions of the event message streams to any one or more of the subscriber nodes. 12. In an event handling system in which a subscriber node receives an event message stream from which it updates a first state therein according to an event interpretation rule, a method comprising: a sequencer node also receiving the event message stream and updating a second state therein according to the event interpretation rule; the subscriber node temporarily losing access to the event message stream thereby resulting in said subscriber node missing a portion of the event message stream; the sequencer node continuing said receiving of the event message stream during the access loss of the subscriber node and continuing said updating of the second state therein; and determining, and delivering to the subscriber node when it regains access to the event message stream, an optimized version of the missing portion of the event message stream sufficient to update the first state to be equivalent to the second state being updated in the sequencer node, wherein the optimized version is a relevant summary of the missing portion of the event message stream based on the event interpretation rule. 13. The method of claim 12, wherein said determining the optimized version of the missing portion of the event message stream includes using a shortest path graph search technique. 14. The method of claim 13, further comprising: the subscriber node using an event interpretation rule in replacement form such that fields in the first state ar
