I have gotten to hear Michael Laine's presentation and speak with him, but that was 8 years ago during the first iteration of Liftport.
I am on PI's newsletter and they are progressing steadily, so they may have some nice shots of their Arkdy-100s. They may also talk up NASA's current plan to capture an asteroid and return it to near-Earth space for manned rendezvous and sampling.
I have heard of Icraus Interstellar, but that is about it.
