This is the way done in many places: visual designers work with the visual tools they master in order to express a visual proposal. Then everybody can discuss about that proposal just by looking at / interacting with a Flash file or something equally easy to access.

In the meantime the developers join the discussion looking at the feasibility of the proposal from a technical point of view, potential drawbacks (e.g. looks good but will give us 3 months of work, will hog the system and will drain the battery, etc).

About running Miniature in the N8*0. There are no official/community plans I'm aware of for porting Qt 4.6 to Diablo. Therefore, either the Mer project gets a Fremantle-ish platform for the N8*0 or someone backports Miniature to the Qt 4.5 bindings available for Diablo or perhaps there are other workarounds.

I agree Miniature would be very interesting in the N8*0 but anyway we need to get it done first in Maemo 5 before thinking of alternatives.
