I think that we should all contact Ledger and ask for them to integrate Zen support into their wallets - I would think it would be easy to do as they already support Zcash and it would definitely increase the exposure and legitimacy of Zen!
Ledger support is on the roadmap. I talked with one of the Ledger owners at Consensus last month to get the conversation started. There is a process, and it costs money, which is fair.
Hardware wallet support is important, and it is on the roadmap.
