Packaging and installation is certainly an issue.  But, I have to say,
if there's one thing that we know a hell of a lot about (for better
and for worse), it's packaging and distributing software, including
software that's difficult to package and distribute.  For example,
before even trying to seriously experiment with OpenSplice, we're
packaging it; here's a first cut at a binary .deb (for 64-bit
Precise):

The license question is also important, but LGPL is perfectly
acceptable.  If somebody tells you that using an LGPL-licensed library
is a problem, you should ask that person whether he or she uses glibc.

Btw, OpenDDS is released under what I read as effectively a BSD
license (though they have annoyingly written their own terms):
