<div class="gmail_quote">As mentioned in #telepathy, I am working on Ubuntu One (U1) which is going to provide a set of cloud based services to Ubuntu Users. Some of those services will involve private proxy servers for Screen Sharing (and perhaps more) I would really like to use Telepathy in this project but, I am unclear as to what it will involve. I understand there are already changes made to vino/vinagre to support these over stream tubes which is awesome. In addition we would like to do is provide our users access to private proxy servers if we can't establish a p2p connection when a Tube offer is made. (This is where I am unsure how this would work) The rest of this email is just some information about what we would like to do, but if you have feedback I would appreciate it. With screen sharing, there are also other things we think we can do to improve performance: * Find ways to increase success of P2P connections using Tubes (libnice changes perhaps) * Decrease bandwidth usage by adjusting options in vino (there's a vino bug for this) * Smart Proxy/Message Accelerator between vino/vinagre? (Idea based on <a href="http://www-cse.ucsd.edu/%7Ecbtaylor/psu.pdf" target="_blank">http://www-cse.ucsd.edu/~cbtaylor/psu.pdf</a>) * Proxy between server/viewer for Compression like NX? (We can't change RFB, but we could create a special client/server proxy) Here are some additional possibilities we are considering for telepathy/empathy: * Connecting our users to our XMPP server * Contacts Presence (Empathy, custom client) * Chat (Empathy) XMPP Extentions and Applications * U1 notifications Server ---> User (via Empathy or custom client) * Bob has shared a folder with you * Bob wants to share his contact list with you... * Bob wants to do this wizbang U1 thing with you (etc..) If you have any questions feel free to contact me (jdobrien on freenode)...I'm usually in #ubuntuone or #telepathy. Thank you in advance for your help, John O'Brien</div>
