Two things:

1) I would assume that you can invest at the same level of risk at existing public company (e.g. micro cup, or investing in options), the this point is mute.

2) core pillar of modern finance is portfolio theory . I.e. how to mitigate a specific company risk by investing in portfolio of companies (which is what VCs are essentially doing). Hence, this would also imply here (regardless of the amount of audit employed). So really a risk of a single company is a non issue.

Yes or no. Google is pushing the mobile web because it can index/rank web pages (PageRank work well with web pages and the links between them). It is much harder to deep link between native apps, hence Google cannot search in-app content. Without being able to rank in-app pages and even whole apps, Google cannot make money.

The other key question is access to the device native capabilities from java script. Google can at max, assure access to android OS API from java script, but even than the device hardware manf (e.g. Samsung) can create additional hardware capabilities which can be accessed only by native apps.

So to sum up, the whole "mobile web app" vision can only occur if Google could rank mobile app pages and show you native apps (or a link to the original web site) in the search results.
