We host around 10 iDirect hubs for several customers, after quite a lot of issues with previous sw versions I don't hear a lot of complaints from the customers on stability, as far as I know the iDirect product has matured. An issue with bigger hubs could be the large number of servers needed for Protocol processors and NMS producing a lot of heat and consuming a lot of power. We run ourselves a Viasat Linkstar hub, this could also be good candidate for the needs of th OP. We are very happy with the performance of this hub. No experience with Hughes.
