I've been looking at Mushroom Networks to bond multiple uplinks. Tonight I found there is another new option: Sharedband which looks interesting. Mushroom Networks has gotten some great reviews, but Sharedband costs $25 per line for business, the equipment is less expensive, and they have multiple locations in the US which should mean less latency added depending on where you're connecting to and from. Here is a review

If anyone has experience with this, I would like to hear about your experience.
