Yeah, the licences of the linear solvers used in IPOPT are really too
restrictive.

I use the ma27 (I think it is called) as academic user. It's not as

You register, you get a confirmation mail with a password, then you
can log in an download the code as a couple of fortran source code
files.
So, not such a big deal.
