It depends on the projector really. Some projectors have a SD card slot where you can put ILDA files on and then the projector will be able to play those files without a DAC.
I found this for you:

It appears that there is no SD card slot so you do need ILDA or DMX for controlling the laser, but there is a Freestyler fixture in that page, ledmuseum.candlepower.us/34/reke50-1.zip
Unzip in the fixture folder of Freestyler and you should find it in Freestyler setup -> Add/remove fixtures -> look for Reke in the manufacturers list -> select the projector -> click on the arrow to add the fixture. That should save you some time programming all the effects. But you can't add your own effects by this.
The Easylase with DMX option has ILDA and DMX output but it is maybe rather expensive... and it doesn't come with software. I'm not aware of other DACs with DMX functions other than the QM2000 and such.
Both LSX and Spaghetti suck at real DMX control though. LSX just isn't aimed at DMX and Spaghetti has a DMX function that was only recently added to the program and you can't even create your own fixtures yet. But I think Spaghetti would be a better option for DMX, as I'm sure it will improve over time.
I don't think that going with Easylase+Spaghetti is the best solution however, but I'm unaware of other options...
Oh and wireless transmitters tend to be unstable. It doesn't sound cheap too...
