Postal Service
Rural postal service hopeless
Details not found yet but postal service believed to be hopelessly bad in rural areas (and not much use anywhere).
Nepalresearch.com has some news reports under telecommunications:

POSTAL SYSTEM IN NEPAL : INEFFICIENT AND UNRELIABLE, Nepal News 2008-11-28
NepalNews 2010-06-28 mentions that salary for 147,000 teachers is paid only once every four months (Rs 4.3 million). This suggests that postal and payments network is inadequate to support even monthly, let alone fortnightly or weekly payments.
Would need to aim for weekly deliveries to and collections from the proposed 800 or so new local district centers. Hopefully that could be extended to a weekly service for schools via the 1200 or so rural markets. Locked delivery boxes for each local school could be provided at each of the 400 or so markets that are not also among the 800 area centres.
Presumably there would be parents of children at each school attending the weekly markets so it should be feasible to arrange pickups and deliveries. This may be simpler for a limited regular service of just flash cards to and from schools than for ordinary postal services as each delivery is expected so any losses would be detected immediately. Presumably regular porter traffic to and from the markets could connect to the area centers.
