There are lots of little ones. One that the government could help to solve is that we want to hire an automotive engineer from Austria, but either have to wait until the H1B's refresh in April or wait for an immigration lawyer to work some magic. The other issues are mostly personal; we can't work as fast as we would like because one of us maintains a job, and that we don't have enough money to setup a lab. We'd need at least a couple hundred thousand for that, though we're looking for a larger investment (x million, not xy million) so we can bring on a few experts.
