I have high hopes for hybrid approaches. Things that excite me on this front:
  • Hosted channels
  • Offline receiving through LSPs
I believe it will be a combination of some network/protocol capabilities coupled with best in class UX for end-users. I don't know whether it will be 100000% non-custodial, but likely a hybrid mix where for some small time period your LSP is holding onto some funds on your behalf. Seems reasonable and achievable.
