I think it would be more of a labour of love than anything else. I think the backend to decoding the packets was pretty solid, and I imagine a conversion to a newer version of QT wouldn't require a total refurbish of the code. I wouldn't want to undertake it by myself, but I think it would be manageable for a team of between 2-5.

To me, the greatest point of failure for SEQ isn't the dependency on QT3, but updating the opcodes for the monthly patches. I know Newby posts a patch within a day of each patch, but does anybody know how to figure out those opcodes? Would Newby be willing to share his expertise/methods with some newbies?
