ALFRED provides almost all the functionality I need apart from the fact that I really need to embed the alfred code within my own application. I could use it as is via a sys call, but it would be so much better to include the code. What are your feelings regarding splitting the alfred code into a library with can be included in other user applications, and an alfred client program that uses this library? I'm quite prepared to give quite a bit of my own time to doing this if you like the idea.

Are you interested in using alfred, or vis built on top of alfred?
Would you want a library for accessing alfred, or for accessing vis?

You could pull some of the boilerplate code out of vis and my
alfred-gpsd server/client into a library. e.g. alfred_open_sock(),
_publish_data(), _request_data(), _receive_answer_packet(),
_get_data(). What will cause problems is the globals structure.  It is
a mixture of generic and application specific members. That will
require quite a bit of refactoring.

I'm just not sure it is worth the effort. It took me less than a
mythical man day to get a proof of concept gpsd code working, and
another day to sort out output formatting issues and the odd bug, etc.
Creating a new client/server embedded in some other application is not
particularly difficult, re-using the existing code.
