I know nothing about your service because all I see is a little bit of text that might as well be a middle finger to the user.

and an adobe icon.

This is definitely a usability issue that we will be resolving shortly. Thanks for the feedback!

Unless you've found a way round it, Flash P2P file transfers requiring loading the whole file into memory - so you can't transfer massive files.

I've read yc news for about a year now and this is the 1st post I've upvoted. Nice app.

Thanks! The app has been a great help internally and we're hoping other people find good uses for it as well.

We've used this little webapp at work to move files around for a while now and just released it to the wild. Would appreciate any feedback!

Few suggestions. - Would like to see the tx speed. - Long file names look wrong in the UI. - Would like to see file size in GB/MB/KB instead of just bytes.

We're definitely looking to add tx speed. I just pushed an update that should fix the long filename issue. Thanks for the notes!

I created a service nearly identical to this about a year ago.

Why didn't you do more with it?

What else would you have expected me to do with it? I mostly built it as an experiment. I was playing around with the new P2P features in flash 10. My first idea was video conferencing (http://www.boostcam.com) which actually manages to more than make up for hosting costs in adsense revenue. If only I had thought to have it connect two random people! This was my second idea. I didn't really think there was much else to do with it. I have some ideas for features, but I have and always will be very limited on time.

Is there anything special about the p2p features in Flash that couldn't be implemented with HTML5 WebSockets, WebWorkers, etc.?

websockets has no passive mode

Yes.

Web sockets are implemented on top of a HTTP verb, e.g.:

{Regular HTTP handshake} {Socket negotiation} {Data sent over the open connection}

Unless your browser also accepts incoming HTTP connections it won't be able to accept incoming requests. It's not UDP as you know it, so you can't just fiddle with DNS or a router and re-direct packets to another JavaScript P2P client.

Hopefully that'll get fixed one day. Direct P2P from the browser would be incredibly useful, but there are real problems with cross domain DNS abuse. For example it's possible to use IE6 visitors to run a search engine spider without their knowledge or consent because of the (reasonable sounding) same-domain-cross-iFrame-read permissions.

Did not work for me as I could not connect to my peer and my peer could not connect to me.

We have an update going in today that will fix a number of additional firewall cases, can you tell me a little about your network setup?

Doesn't work for me. Still waiting. Firefox, Windows 7.

name is very web2.0. So it's using the flash p2p functionality like chatroulette?

Like it a lot, there are tons of applications for this.

Yes, it's server-assisted p2p. It's a great tech for getting around firewalls and serves as an effective solution to the "I can't send you the file for some reason" that we were running into daily with our various IM clients.

Glad you like it!

Please Wait...

Still waiting... In all of Firefox, Chrome and IE.

Our firewall is an MS ISA server. There is websense in between. The browsers are configured with an automatic configuration script (a .pac file).
