A couple of issues here - we don't know what the IM infrastructure will comprise in Fremantle, so probably not a lot of mileage here until we know how much Nokia have done on this, also, getting it to install properly shouldn't be a really big problem (he says).

Contact import - again, we don't know what will be available in Fremantle (yet), though I like the thinking.

Syncing support might be useful in general, would need to ask some questions of Nokia as to whether they are already planning on using/already have such a thing.

And don't be afraid to edit the wiki, just go for it!
