As I understand it, Your "joint-venture" actual will improve without "selling out", i.e. in the mentioned case You get a faster seacher without degrading the "brightness" of the application! Sounds that we all have a lot to look forward to! BTW (it must have been quite an experience for Ed - as a rather "loner" to start exchanging idears... years ago I speculated about what would happen if Lang and him went together and now we all see an equivalent - for sure very, very promissing!) All the best, kim
