Rails - Aug 2005 - Ruby2Exe + Rails - any reason why this shouldn't work?

A friend was mentioning how he used Ruby2Exe in a project where the
client didn''t want to install ruby on the machines and it worked out
well for him.

I was taking this idea and then wondering whether there would be any
reason one couldn''t do this with rails too. In fact I was thinking
maybe this resultant exe could launch rails and then even spawn a
thread to launch the user''s defined browser pointing to the rails app.
Basically they would launch a single app and they would be presented
with a browser already to use the rails app (assuming that database or
whatever is already available on network).

If this would work then one could introduce Ruby & Rails in places
where clients might have traditionally used a fat client. And yes
there are limits to what Ajax can do compared to a full desktop
client, but for somethings this would be fine. And the zero install is
a nice capability.

So my question is: 

Does anyone see any reason why ruby2exe + rails wouldn''t work?

Thanks in advance for any thoughts and suggestions.
