Rail looks promising, insofar as it isn't dependent on the style of seatpost clamping mechanism (c/f Alpkit's Exorail).
Webbing ladder fastening system is interesting, but I'd like to see (if there is) some degree of adjustability to take up slack after the buckle has been engage with the webbing.
Yeah I said the same about the rail, it could be decent to just hang a drybag off. Looks like a very similar clamp to the bagman they sell, just with capacity for these rails on the outside
