Then again, maybe we don't *need* all the functionality that DBI offers.
DBI is enormous, has a lot of extensibility, cross-database
compatibility ... and, well, just the fact that it's a layered design
(requiring a DBD on top of it before it even works) makes it even more
complicated.

I think a pure-perl standalone driver might be a lot simpler than
maintanining our own DBD ... and we don't have to convince animal
maintainers to install the right version of DBI in the first place.
