I have created a git repository for X11rdp-o-matic on Github at https://github.com/scarygliders/X11RDP-o-Matic
Read-only access is via : git://github.com/scarygliders/X11RDP-o-Matic.git
As it stands there is only the master branch which is based on Version 2.5
I am now beginning work on V3.0, which hopefully will start using the latest git versions of X11rdp and will include support for the latest iterations of Debian, Ubuntu. I also intend to start including support for RPM based distributions in the future.
