IL2 CoD on two computers?

[Katana1000S]

I have the collectors CD edition that requires Steam, am soon going to be building a second Sandy Bridge PC just for flight sims but I'll still use this I7 920 a lot ... is it possible to have IL2 CoD installed on both computers? I'd only be using one install at a time ... I know you can do this with RoF.

I think I saw mention of this on here before but never paid too much interest and cant find anything in search.

Cheers.
