Luca,
I'm not using rectifying software on a daily basis, but I can't remember
any other piece of free software for doing rectifying and georeferencing
(photomosaic, that ugly term.. :-), with the exception of Walldrawer,
which doesn't really does rectyfying but just low-quality stretching of
the images.
However, the GRASS commands use knows algorhytms to do their work (and
they're GPL'ed), so I think it wouldn't be too difficult to build an
application with a simple GUI that does just rectifying and
georeferencing based upon a known working algorhythm (just like Rollei
MSR, or MicroMap, for those who know them). Obviously, this means time
to spend on such a project, but we can put our little efforts together
at least.

Please let us know what you all think about this. Thank you,

Stefano
