I need atomic actions across an N number of application servers. The goal here is scalability, which is why I brought up clustering. Unfortunately, we really do need those transactions :(
Thought has gone into solutions other than a relational database but they all ended up at the same place ... we started to design a database. Basically, we need the features of a relational database so other solutions started to look like one.
thanks for the help,

Consider pgpool, and look at the partitioning feature (which uses
different machines for different records, allowing writes to happen very
quickly).
Also, depending on what your needs are, a relational database might not
be right for you. You say you need transactions, but if you're comparing
to MySQL's master-master, I don't think that even supports ACID
transactions. Do you actually need transactions, or just many writes per
second (perhaps to memory rather than disk)?
