Running headless & CI

Hi Folks,

Here's what I'm trying to do and need some advice: seems that FlexUnit 4 in its Beta 2 incarnation will not run on a headless Linux CI machine but Fluint will? Is this a correct statement so far? So looks like for now going with Fluint is a good idea until headless is supported in FlexUnit 4?

Also, we're a small shop and TeamCity being free for under 20 users looks pretty sweet, but is there a better system to be looking at in terms of integration with FlexUnit 4 down the line as it matures? Has anybody had luck integrating TeamCity and Fluint? What CI system would you guys recommend?

Thanks for the advice,

Joe
