We are have an alpha version of DirectRT v2010 out for testing. Licensed users of v2008 are free to download and play around with it in exchange for feedback re bugs, features, etc. The next release of the alpha should be available next week and is expected to have dual screen functionality. The current alpha version actualy DOES this now, but the overall window size is limited (it needs to be run in "Windowed" mode). We are trying to eliminate that limit so you can have access to two full screens.
