There is a new version of SOAP2DCOP bridge. It is multithread (based on Qt's QThread) and it is intended to be ran as a program service. At the beginning of the application the server thread is started and at the end it is killed. You should then export dcop calls to soap, but that should be fairly simple based on my example. If anybody needs DCOP over the net, feel free to take it from my repo. The module itself can be found here, but you should use mercurial to clone the repository:
hg clone http://tesla.rcub.bg.ac.yu/~brcha/hg/Opstina.hg
And last, but not least, you should first download your copy of mercurial version control system from here.
