Hey there -
I've used iTap RDP for a while now and have been annoyed with the inability to do a "quick connect" session like CoRD and most other RDP apps. So I've written a quick little Alfred workflow to open an RDP session from a temp file (I can't believe I didn't think of this before!)
The workflow has been (lightly) tested with both iTap RDP and the newly-released Microsoft Remote Desktop app (free from the App Store), but should work with any other app that can read a .rdp file.
Usage:
Type rdp <hostname/IP>[:port] (port defaults to 3389)
Enter will open an RDP session to the host using the default system application (can be set using APP variable in script)
Provide a "short hostname" (non-FQDN hostname) to auto-append the search suffix from /etc/resolv.conf
Download direct at GitHub.
Enjoy!
