+1 for flex;

I am using a xubuntu 64bits distro as operating system. recently the 
people at adobe released a 64 bit pre-release for flashplayer 10 and it 
works like a charm here. It is good to see that adobe is putting effort 
into 64bit too.

The adobe air platform is also moving to maturity on linux, so that is 
another good thing to guarantee a large user base.

As an example; the french gendarme is completely moving away from 
http://afp.google.com/article/ALeqM5iU4Lq7tOR_WVOJLZ3IeRaIH03x6w and 
becoms more and more linux based. It seems to may that governmental 
bodies like this could really benefit from a good mapping application 
that is no longer depending on ocx's or other windows only 
architectures. I would not bet my money on microsoft silverlight as an 
alternative to flex.

Mapping with flex would really "light my heart"!
