If you implement one feature, I will switch immediately: multiple accounts running at the same time.
I want to be able to sync my work stuff completely separate from my personal stuff. No "Shared Folders" solution or jazz like that. Dropbox seems totally unwilling to support this officially, so if you did, that'd be an awesome differentiator.
I'm not sure if this is exactly what you mean, but, last time I checked (a while ago) you could share different folders with different computers. For example, you could make a "work" share and sync it only with coworkers, and a "personal" share and sync it with your personal computers.
The problem is if me and Joe use Dropbox for personal use, and then we come up with a great startup idea and want to start hacking on it. On like day 5 of working on this idea, you'll want to start sharing/saving some PDFs or excel sheets or something. Ideally you'd be able to create a new Dropbox for this project and run two clients on your machine, one for your personal Dropbox and one for your new project Dropbox, and Joe can do the same.
But because you can't run two clients at once, you can't do this. You can create "Personal" and "Project" folders in your existing Dropbox and sync to different machines, but Joe now needs to use your Dropbox account and he can't sync his personal account. Or you both use the web client, except you're basically using FreeDrive from 1999. Or you use an entirely different file sharing service like ZumoDrive, which is kind of silly.
I get that multi-client support for Dropbox is probably a niche feature and will probably lead to jerks like me using 5 accounts instead of 1, so they don't do it. And there are workarounds like Dropboxen that allow me to sort of have multiple Dropbox instances running on my machine if I have multiple user accounts. But man it'd be nice if multiple Dropbox instances running was a native feature instead of having the same, "Ok, I filled out the Articles of Organization and put them in my Dropbox so just refer to our filing number from there."; "Why don't you put them in MY Dropbox and YOU just refer it from there?" conversation with Joe.
The issue is that it's being shared from the same account. I know about Shared Folders and use them extensively.
In a nutshell, here's what I want:
- Install Dropbox
- configure account #1 : email@example.com
- configure account #2 : firstname.lastname@example.org
I don't want anyone at work seeing my personal email because it is, well, personal. No-one at work should need to know about my personal stuff unless it really is personal. Dropbox doesn't seem to understand the value of this.
I want to keep my work life and my personal life separate and many new services don't seem to understand or value this.
Ah, now I see what you mean... I circumvented this by using my work email to have invitations sent to, but accepting them from my personal account. I'm not sure if the people in the share can see my email address, though.
To echo your update on the original question: while AeroFS is a distributed filesystem with quite complicated mechanisms underneath, we work very hard to make AeroFS dead simple to use. Following this philosophy, we've implemented the features that you mentioned but they're currently disabled/hidden for the sake of simplicity.
Regarding offline computers: if the only computers that host a file are offline, the file data will be unavailable. Currently, offline files are invisible in Finder/Explorer/etc. Because the current system only supports full replication, having offline files should be a rare case.
Regarding performance: it's crucial to us. Lots of efforts has been made (and even more to be made) to ensure the filesystem has comparable performance to local storage; sync performance is another area that we invest a lot of time in.
