Two MySQL Server accessing same database over NFS

Question

I want to run two separate MySQL instances on two separate machines, but using same data directory over nfs, is it possible with InnoDB Storage Engine? Application operation will assure the following:

• one MySQL instance will be a producer
• one MySQL will be read only consumer

On the MySQL site, it is mentioned this possible with MyISAM and merge storage engine only, but they never recommend it.
