I'm on it ;) Seriously! (in regards to disrupting the SAP business)
Interesting. If you're willing to talk about what you're doing at all, drop me an email. I'm working on an enterprise focused startup as well, maybe there's some synergy to explore or what-have-you. If we're not pursuing the same space (and we aren't doing anything ERP related, per-se) then - at worst - we could bat some ideas around and maybe help each other out in some fashion.
Hey, that means I'm not the only one thinking about start-ups and products in this area. And I totaly agree, SAP's business is about to be disrupted. The only point is, I'm not sure the time is right yet. And when it is, it will be quite a battle... And that's exactly why it's worth it.
