Option 1 would mean creating a transaction object and an info or check 
command for it?  Certainly option 1 holds more historical information. 
 But option 2 would be easier to implement...

I guess option 1 seems like the most versatile and useful, so my 
preference is with 1.  Could client trids still be optional if you went 
ahead with number 1?  Does it even make sense to keep them optional in 
that case?
