I saw one of these at REI the other day, but couldn't remember the name or find any info at Nemo.com. It is designed to be a day-hike shelter. While it doesn't seem to be big enough or practical enough to be a solo shelter, it might work as a 7.5 oz porch or cook area for multi-person trips, augmenting a tight 2P shelter.

Edit: then again, maybe a solo shelter. It can be pitched as a small 'mid, but I can't figure out the usable length, especially with a center pole.
