Actually, N-Grams scale very efficiently. I wrote a simple mp3 library manager, that uses N-grams on the ID3 tags of my mp3 collection, which is well over 60GB. Storing the N-gram of every song's ID3 only takes up roughly 1MB of RAM, if that. I would say for anything web2py would be used for, N-gram based search would be kicken. (come to think of it, since I have the n-gram code in python anyways, plugin time :P). Unless you store as much data as a googlebot, I don't think you need to worry.
