I found a supplier. Try SamTec part number SQT-116-01-F-S.
I order a batch, they came in last week and they fit perfectly.
I use VirtualBox running Ubuntu on my OSX box, and that works great.
My current development environment is Eclipse (CDT) using the tool chain that is built as part of the instructions on the wiki. When you create your Eclipse project(s), you specify the tool chain location, etc. I simply copy the generated binaries over to the Omega and I'm off to the races.
FWIW, I use two build profiles within Eclipse, 'Release' and 'Unit'. The Release profile cross compiles and generates Omega binaries, the Unit profile is for unit testing and generates native (Ubuntu) binaries. This way I run all my unit tests locally and then, assuming all unit tests pass, push (scp/rsync) the Release profile generate code to the Omega.
