According to the pilot, the ship is following unmanned probes. What if that assumption is wrong? What if they're not unmanned? A million year old stasis corpsicle crew, waiting around to wake up for good reason. If the ship catches up, will we meet some Ancients? Will the show give us alien speaking instead of English speaking, for once? More work, but more interesting too.
Plus, the Ancients created humanity in their own image. They look human enough on the outside. Although based on the one they found frozen in Antartica, were quite different in actual functioning. Although that one was frozen during the great plague which nearly eradicated all life in the Milky Way. She started picking up English in a couple days without any sort of translator though, and had healing powers more like what you'd expect out of an anime character.
I must say though that the ethical issues generated by the communication stones are quite intriguing, and I hadn't really considered them until you brought them up.
I had no idea that ansibles were a real world idea. Regardless, they don't exist in Stargate, at least not by that name. The SGC uses subspace radios as I said. What the Ancients used seems to have been a combination of conventional(that is, unremarkable to SGC personnel) communications, and the communications stones for extreme range transmitions.
The Asgard it is never really mentioned how they communicate. However their engines were by far the most advanced in the series, and it was the one technology where they clearly outstripped the Ancients. They could travel the distance between Galaxies in mere minutes. Which indicates to me that they might simply not have long range communications capable of crossing between galaxies. They never used such a system as I recall. When they wanted to contact Earth they always traveled there by stargate or by ship. The only indication of long range communication was that they could be summoned by a signal from one of their protected planets where SG-1 had disabled the primary fixed defenses. They responded incredibly fast.
Really if the Asgard were still around, they could probably go out and rescue the passengers in a couple days tops and drag Destiny back to Earth. Too bad they aren't around.
