Installing RhoElements on a non Motorola Windows Mobile device

Can RhoElements be used on non-Motorola WM device?

I've a customer that is willing to use RhoElements with the ES400 he is now evaluating, but the old devices they're currently using are not Motorola and they are not willing to upgrade all of them to Motorola devices.

They are currently using the Dorothy Webkit based HTML5 browser (which has no support at this moment) and they want to use RhoElements if is possible even on the other devices.

Their need is to use it as a plain web-browser, with no additional hw support.

What are the best practices in this case?
