Re: Outrigger. Jini2.1

Mahalo can be used on different spaces.  So write to space1, and write to
space2 can both be in the same transaction.
However, watch out for the scenarios where Mahalo crashes, it may be
possible to have one node committed, and the other node not-committed from
my understanding.  To avoid future surprise, you may wish to ask about
this type of questions to the wise members of this list who are much more
knowledgable than me on this area.
