There already is the tango.phobos project at DSource which contains a "port"
of Phobos, although unsupported by the Tango team.

It has changed all std. to phobos. and been made to work with the Tango
runtime. There are a couple of catches with this version. Firstly,
threading is tightly integrated with the GC and as such the Tango threading
should be used, secondly it has afaik only (or mostly) been tested on Linux
and with DMD. 

What is there should be up-to-date with DMD 1.004, but no guarantees. Anyone
who wants to get involved are free to do so :)
