Thank you. The OS's for options 1, 2, 3, and 4 would be, respectively:
1. OSX (10.10+) or Linux (not sure which, but a stable release from 2013
or later)
2, 3, and 4: Windows 7.
So just to be crystal clear, am I right in saying that it is your
understanding
(with the caveat that you're not giving me legal advice and I need to get my
own lawyer to do that) that if I never static link (and always dynamic link),
and I include the proper notice provisions related to FreeTDS's license, then
under options 1 or 2 (as well as 3), I am not obligated to disclose any of my
company's proprietary source code or object code (other than executable
binaries)?
Again-- sorry to beat this one so much but staying within the bounds of the
licensing while keeping our code closed-source is extremely important to us
and is the only way we would be able to use (and in doing so, potentially
contribute to) FreeTDS.
