Just continue. This look very promising. Maybe I should quit my job as
a maintainer and work "full time" at the agents ;) j/k. You should
take care of designing a nice object model. This isn't difficult for
the data (just copy the c structs) but functions are spread all over
common/* and you may want to assign them to other classes.

 "From what I am reading Win98 and NT5.0 will be getting rid of all that
  crap anyway. Seems that Microsoft has invented something called TCP/IP and
  another really revolutionary concept called DNS that eliminates the
  netbios crap too. All that arping from browsers is going to go away.
  I also hear rumors that they are on the verge of breakthrough discoveries
  called NFS, and LPD too. Given enough time and money, they might
  eventually invent Unix."
