So many questions...

1) Does it work well with huge files? 1GB+ etc? Will a 1-byte change mean complete download to all devices?

2) Does it work well with 100k small files in deeply nested folders?

3) Will you charge for software and/or support?

4) What happens when one of the devices doesn't have enough storage? 4GB SSD laptop vs. 100GB HDD.

5) Will any of my computers have to be up 24/7?

This is just me throwing out a toy idea here, but.. Consider that most computers have large chunks of unused space. Now draw a parallel to projects like Folding@Home which make use of unused CPU cycles for computation. Wouldn't it be nice to make use of the world's unused storage in exchange for providing your unused storage? This made me think of that as it sounds like this 'p2p supercloud' could be just another peer type. You opt in to share 100GB == you get 80GB of redundant off-site backup for free type system.

Now, I am not asking you to implement this peer type (although that would rock my world if you did), but would it be possible for someone to implement it themselves? In other words will you be providing a 'peer API'?

"Each AeroFS device has its own 1024bit RSA key pair, which is certified by us to be authentic."

That suspiciously reads like the AeroFS people get a copy of your key. If that's the case then it's only marginally more secure than DropBox. Hope I'm reading that wrong...

I'm curious to know more about the technical details about how this works. Like what protocols and technologies you're using. If that information isn't too sensitive that is. :-)

I think the consumer market for this doesn't care how their files are backed up. They just want it to work.

This offering sounds like a hybrid of Crashplan and Dropbox.

Could be quite good for the use cases they specify.

Two questions

1) How does this system handle two devices behind separate NATs? (aka a work device and a home device.)

2) What is the conflict resolution protocol if a file is modified in two or more locations? (Newest wins, automatic duplication for manual resolution, etc.)

On another note, without yet seeing the software, I'd assume the Mac and Linux ports are both using FUSE. Is there a FUSE alternative for Windows yet?

So it's Dropbox but without the requirement for a central cloud component? Is there anything I've missed?

I like the "Chat with the Founders" on the website... Is that something you built?

EDIT: Thanks guys.

I see your company doc on "How To Earn HN Karma" has worked out well. Now if only you could turn karma into money...

Edit: This is a reference to the picture on their signup page.

Can I share stuff with my friends? Suppose they already host my backups and I host theirs, can I easily give them access to some of my files?

Does it use P2P transfer or the owner of a file should update as many copies of the file as peers syncing?

Way cool guys, and way to represent the Toronto startup scene!

BTW, loved the reference to HN karma in the screenshot!

File syncing that includes mobile devices seems to becoming increasingly important as their storage space grows. I'm excited about AeroFS and am looking forward to seeing more posts about the technical aspects.

What about performance? I assume since many routers these days use asymmetric dsl, download/upload from hosts may be poor if only a few hosts are involved, and the hosts use ADSL.

Could someone clarify the difference between aerofs and rsync? What can aerofs do that rsync doesn't?

Anyone have invites to give out?

a wrapper on top of git, I guess? ^_^
