Essentially i think it just takes interest/demand from ISPs since the mechanism can be implemented and deployed without in a non disrruptive way. Crying about protocol deficiencies is a distant second to keeping aimho, protocol efficiencies are not so much the problem. If it is clear the scale routing must operate on the right hardware/software can be engineered... that assuming that people are willing to upgrade their existing boxes and that it isn't a requirement that it must run on 5 year old small entreprise boxes. The later seems to be the biggest problem although. Effectivly the growth of routing table size is bound by the maximum memory size and CPU capacity present in the most common boxes used in the network and not by protocol efficiency. It is not so much of a question if one can build a database engine and respective distribution protocol than can scale upto n million paths but of the limits of the current day moral equivalent of the AGS+. Thus all the people that have these deployed in their networks tend to be concerned about the need to upgrade them as the size of the routing table increase. As one of the posters was king enought to point out these sometimes end up being more issues of economics/buisiness than of engineering. regards, Pedro.
