Haven't tried the "mixed effect" analysis myself but it's already
available in SPM8, though not through the GUI.
Look for a function called spm_mfx.m and check the help within.

> "PS Regarding the implicit assumption that error variance is constant across subjects, could this be addressed through a mixed-effects analysis in SPM? i.e. Friston et al (2005) Mixed-effects in fMRI studies. NeuroImage 24, 244-252. http://dx.doi.org/10.1016/j.neuroimage.2004.08.055"
> I think that's right. I haven't looked into the issue enough to really decide though.
