Linkbuilding for a Flash based website?

How should linkbuilding be done for flash sites?

you do it just like other ones, you have no way, except onsite SEO is kinda impossible, all you can do is the META

The content/type of the site will not interfere in the link building..

The only concern is if google will accept the flash as a content if not it will be more hard to gain positions..

I have this website which I have promised to get to top 20 for a keyword. I've done xrumer, profile links, blog comments, article submission, social bookmarking and it is not even in the top 1000!. The keyword is 2 words and is in the title, description and meta.

Any other ideas?

If you have no content on the site you might want to consider setting up a keyword domain and cloaking so that spiders see content and visitors are redirected to your flash site. The forwarding domains are throwaway because of the risk.

There's a few posts on this in the cloaking section and there's a WP plugin that seems to do this quite easily, haven't tested myself yet though.
