I've added all the big mining pools to my addnode list and also increased my connection limit to 400.

Is there anyway for you to display which mining pools have seen and are relaying a particular transaction? You could then calculate a rough estimate of how much hashing power (and what percentage of the total known bitcoin network) was aggregated behind an unconfirmed transaction. Imagine a table with the major mining pools, their hashing power, and a simple yes/no if they are working on a given version of a transaction. The chance of a double spend after all the major mining pools are working on a particular transaction would be slim to none.

This information could help implement Satoshi's suggestions to the so-called "Snack machine problem" and significantly reduce any risk associated with accepting a unconfirmed transaction (http://forum.bitcoin.org/?topic=423.msg3819#msg3819).
