This is probably a little different from what I described. I guess, with your open office plugin, nutch talks to a running open office instance via uno at certain port? I may be wrong. What I want is the ability to start up an external program (say, written in perl) as separate process and pipe in/out bytes through it. It might have less to do with plugin, but I want to make sure it is not impossible with plugin. > The code isn't 100% compatible with our actually plugin -system > implementation. > Until this week I have vacations so I can put it on my to do list for > next weeks to update the code.

But, A depends on C-version1, B depends on C-version2 and C-version1, C-version2 are proprietary, i.e., I can not change them. Could you be more specific?
