It is a little though behind the DB15, and what really tilted me to go for it are these:I know this is probably way too late for this and maybe no-one agrees with me, but I personally hate the DE-15 connector. Making cables for it is a PITA.
Any chance of an auxiliary 5 pin connector with just RGB, sync and GND?

2.5 bucks and you don't have to deal with crimping, getting the right connector and whatnot.
Also, the jammafier has the option to output 5V on pin 9 of the DB15 - so making some kind of thing similar to the one above, but with active electronics should be a breeze.
