It is possible to extend the VPI for Icarus Verilog.

In particular, I'm nearly finished with a draft of the newest
development path (It's been a big job for a big change, which is
why I've been quiet for a while) and that would be the preferred
baseline for new features.

The new VPI capabilities most likely to get added quickly are those
that can be implemented entirely within the vvp binary. Data flow,
simluation events and static objects of all sort are easy, VPI access
to uncompiled behavioral source is harder.
