If the results are correct (it's 12 years old, I don't know if the findings have been challenged since) then we would seem to have a steady stream of interstellar particles from at least 2 discrete extra-solar sources. I wonder if there would be value in a Stardust-like probe - perhaps in Earth orbit - aimed at trapping micrometeor particles before the impact the atmosphere. Or even the high-altitude 'fly paper' flights, intended to sample interplanetary dust particles (McSween refers to this in Ch 1 of MATPP). Either approach would seem to offer the opportunity to realise a proportion of specimens which originate from outside our system. I've no idea how they would be positively identified as such, however.
