Yes, omniORB is free. Under the terms of the GNU Library Public
License, you must make the source code to omniORB available via the
same route you distribute your application. You do not have to make
the source code to your application available.

We do not provide commercial support. The only support is informally
via this mailing list. You can look at the mailing list archives to
get an idea of what this means.

One performance comparison is at

I would strongly recommend that you use omniORB 3.0 and the POA. You
are going to have to modify your Visibroker code anyway, since BOA
code is not portable between ORBs. The POA makes many things much
cleaner. It also provides a simple migration path for your application
if you need to start using more advanced facilities which are
available with the POA, but not with the BOA.

Due to refactoring of the code, 3.0 is actually smaller than 2.8 in
some aspects, so you shouldn't worry about code size. 3.0 is also
where our development is centered, so if you find any bugs, they are
much more likely to be fixed in 3.0 than in 2.8.

Cheers,

Duncan.
