I have a wiki currently, which is easily accessible and updateable from anywhere by web. Is that something that org-mode can provide, or do I need to ssh into a machine (ie, harder from a mobile device)?
The main problems for me are:
1) Keeping everything synced. Especially Emacs's state.
2) I don't trust a VPS with all my personal information. I have *everything* in org-mode files.
The first problem can easily be solved by using a tmux session that is shared between smartphone and laptop. The drawbacks would be that I can't access said session without Internet and also that I lose emacs's gui features like the pdf-reader. x2go is fast enough but they don't have an android client. I have yet to try nomachine.
