eMunie supports it, and has been a requirement from day 1 of the project.
Our ledger also supports partitioning, where nodes can elect to store only a part of the entire ledger. This is to allow storage limited nodes to still provide value in regard to securing the network.
With this ability, even if the network is seeing loads 100s or 1000s of times greater than what BTC is currently, low resources devices such as Pis can participate without needing terabytes of storage available to them.
The hyperbole is strong with this one. We've been running alts on Pis for years, btw..
Supporting a network with a Pi that is processing 1-2 tx/s a sec (BTC average) is childs play.
Throw a Pi on a network that is processing 100+ tx/s with current block chain tech and lets see how far you get then. At 4GB a day of transactions at 100 tx/s (1.5TB over a year) good luck with that. Even if you had the storage, and let alone keeping up with the chain, you'd need GB upon GB of RAM just for the UTXO.
Infact Id like to see
any currency support that on current block chain tech and not become centralized to a few farms of full nodes controlled by a handful of people.
Another benefit of having partitions, and channels within those partitions, it allows client-only nodes to not have to rely on 3rd parties for the storage of their wallets. These devices (such as mobile phones) can just store the channel their transactions are in, maintain their own micro ledger with regard to their transactions and not have the worry of xyz.com running off with funds.
