I just poked, and I see there is a TxStats.getInstance() method. Is that 
a valid API for accessing this?

I guess this is referring to our CoreEnvironment bean which does have a property called socketProcessIdPort which we use to facilitate creation of unique ids and it also has a property called nodeIdentifier which we use to ensure that different recovery managers don't end up recovering each others transactions. But there are also other properties in that bean which your snippet does not mention.
