Hello FreeRDP developers, I would like to introduce you to Roman, who is going to be working on implementing RemoteApp support as part of the Thinstuff Summer of Code 2011 program. Roman is quite new to FreeRDP development, but has experience with GDI which is a good asset for RemoteApp. Plus, Roman appears to be a fast learner, so he should be good to go :)
I started gathering information about RemoteApp on the wiki: http://www.freerdp.com/wiki/doku.php?id=remoteapp I added a new sample packet capture on the wiki, and started analyzing the packets to compare it with the spec. First thing I noticed is that mstsc.exe registers three virtual channels: rail, rail_ri and rail_wi. Thanks to Roman who hunted down a post on a forum, it appears that rail_ri and rail_wi are virtual channels mistakenly registered by mstsc.exe, meaning that the only "real" one we need to care about is rail (RAIL = Remote Applications Integrated Locally, a name that comes often in the RemoteApp spec). I will be guiding Roman through his work, and hopefully we should get RemoteApp support soon in FreeRDP. If anybody else wanted to work on it in the meantime, please contact us so that we can avoid duplicating the work. I would have one architectural question to start with: should RemoteApp be implemented as a virtual channel plugin, or be put directly in the core of FreeRDP? RemoteApp is mutually exclusive with the regular full desktop remoting. For the regular full desktop session, the protocol part is handled in libfreerdp-core, and the graphical messages are then handed off to each UI for them to properly handle. Since RemoteApp is basically the same, but for an individual application instead, I think it should be put in the core as well. However, since most virtual channels are handled through separate loadable plugins, how do I go about registering a new virtual channel directly in libfreerdp-core?
