It's a very pretty plant. I think 'weed' is pretty much an understatement, though. I saw a programme a few years ago on the destruction this plant is wreaking in the Mediterranean, and around the Californian coast and I think 'pernicious menace' is a much more applicable term!
That said, somehow I think it'll be a bit more manageable in software form - unless it mutates into a virus and brings down the global infrastructure! I'm just saying!
