Ask HN: What can I get away with at SXSW.

This is a throw away account.

My startup is launching @ SXSW this year. I am considering a purple cow marketing strategy to get noticed by some of the leading tech bloggers. But some of it may be considered questionable, or 'too friendly'.

For example, leaving an Iphone 4G behind at a meeting, then text messaging him/her our pitch on said iphone, but never asking for the phone back.

Aside from leaving an envelope full of money, I'm considering all options.

I've never done anything like this. So what can I get away with.
