I agree with GDTD that it is a tremendous amount a work for a fairly small gain. I think that employing the jailbreak gives one a great deal of flexibility to do pro-like work on an RT.
There's a couple of great text editors (Notepoad++, SciTE, MicroEMACS, Vim), a couple of C# IDEs (QuickSharp, SharpDevelop), two source-control clients (Subversion, Fossil), Python, Perl, Lua and NodeJS, WinMerge.
There really are lots of options for doing real work on the RT without going nuts with Remote Desktopping. No, you're not going to have access to Visual Studio, and compiling C or C++ isn't available, but if that is the subset of development activities that is most important to you, you can always go Surface Pro.
