With the Spitzer guys actually "imaging" the hot spot on one of the hot Jupiters and other guys "imaging" a surface of Altair, I thought we could try to speculate on whether there is some indirect way of detecting the first exomoon. Especially that they not necessarily have to be tiny. I guess accreting or capturing bodies larger than Galilean satellites is possible. So, any ideas? Interferometry, transits, whatever?

Regards,

There is a chance we may find more than just moons in transit. Luc Arnold has theorised that artificial objects could also be detected in lightcurves during transit if they are of sufficient size:
