I'd wait for the DE2 release... ;)
BTW Q2-port is also a good solution, McZonk is working hard on it and it's progressing fast...
Q1 is IMHO too limited and aslo still unfinished... :(
LTE2.0 is a bit buggy, slow and it's much harder to make the FPS based on it... And the project seems to be dead, there are no sources...
Iris - very early beta, cancelled project, no future... :(
