hi, i wanted to have a sequence generator that increments by x value
everytime it generates a value. if i would create the sequence
generator by using the datastore, it is likely that data contention
would occurr if there is high access times.

i have looked into the sample code of max ross in the google code
repository (SequenceExamplesJDO.java) and  think this is limited to
increment by 1 only and not increment by x value.

if sharding technique is used, my concern is that i might not get the
right sequence.

what is the best/elegant way of doing sequence generator that
increments x value?
