I like the idea of a prorated subscription! Nice work. Also, I think Wallet of Satoshi (and probably a few others) only allow adding a limited characters to the LN note/memo. I think in WOS It's limited to 32 characters. This would mean users of such wallets would not be able to paste their entire public key. However, I think it's more of a WOS problem.
It would also be nice to have a QR code displayed that automatically handles this for the user after they input their pubkey on the input field of the website.
I'm going to test it out with another wallet.
