Hi All,
As the title of this email says, there are some nice developments happening
with RemoteApp in 1.0. I am very close to getting it usable. It's currently
getting good, but not perfect yet, there are a couple of glitches to fix,
and we're not even talking of all the advanced crazy features we could add
in a RemoteApp client. A lot of information is sent by the server, so very
deep integration with the local OS can be done, it just depends how much
effort we put onto it.
Here is a screenshot showing multiple applications running over RemoteApp:

The local OS is Ubuntu 11.04, and the test server is Windows Server 2008 R2
SP1. I have exported the command prompt as a RemoteApp program with the
alias "cmd", so the command I'm using to connect looks like this:
./client/X11/xfreerdp -u username -p password --app --plugin
channels/rail/rail.so --data "||cmd" -- 192.168.1.200
Don't forget to prefix "||" to your command alias, which is needed for some
reason.
One interesting thing to note is that RemoteApp can work with RemoteFX, so
you can add --rfx and you'll get a RemoteFX RemoteApp session. The way it
works is that the server draws everything on a hidden backbuffer, and then
gives you all the information necessary to know what is a window and how to
cut it out from that backbuffer properly. Because of this, there's no
difference between regular RDP and RemoteApp for drawing operations.
At this point you'll get some windows improperly refreshed, focus out /
focus in and it'll be ok. I'm pretty sure it has to do with X11 event
handling and forcing a redraw. I might as well figure it out very soon
anyway. Drawing is quite slow for large windows since I'm currently copying
the entire window region every time (very inefficient). I'll improve the
code later on to only draw on windows which have an invalid region, that'll
boost performance a lot.
Feel free to give it a shot now even though it's early support. Things
should be improved soon.
Best regards,
- Marc-Andre
