thanks a lot for your answer, and yes, I like playing with fire :-) (at least while we're talking about exploring new technical seo frontiers)
I've changed the homepage from static to ajax driven now, hoping for Google to treat me nicely.
The "1" is a typo (actually there are lot of typos and "funny english" in the starting post :( - sorry for that)
The ajax subpages fare well so far in Google SERPs, but the homepage had a lot of problems being indexed properly.
I'll see if that changes now that the homepage uses ajax and the meta fragment as well.
What is actually nice it that Bing is playing along quite well - even better than Google - in understanding the site and displaying it (and the subpages) in Bing SERPs. Not even using the Bing WMT.
The need for perfect implementation was what got my going in the first place.
As an advice for anyone willing to play with fire (e.g. ajax site) as well:
Use only ASCII characters in your ajax urls. Otherwise the differences between browser implementations regarding encoding as well as search engines will drive you nuts.
