I can host the file, at least until we get an idea of how much *simultaneous* bandwidth usage we are talking about. If it overloads my bonded T1's, I'll have to shuffle some stuff around and/or remove it... but if simultaneous transfers do not put too much stress on my frame connection, there should be no problem.
In fact, if you can split these up into 3 or 4 files that people can download individually at a time, it may ease the stress and not cause any problems.
You can PM me if you want more information on where you can upload it (and I'll get your account created).
