Right I was just finishing LoTSB for one of my Shepards. Now remember when you talk to Liara afterwards she mentions that the SB was still looking into Prothean Data (and for). So ether this was a hint for us to suspect that the protheans will have more involvment in ME3 as well as the possiblaty that he (the Prothean) was what the Shadow Broker was looking for.
