Hello,
We used bridge to call functions of com sever dll from squeak. We succeeded only when calling very "simple" functions. We failed to get non ASCII characters, decimals when decimal separator in windows is not dot. Bridge can operate in two modes: sockets or direct. Direct mode IMO have problems with releasing windows resources. We saw growth of used handles with every call in Process Explorer from Sysinternals. We had "hangings" when tried to call SOAP method that in turn calls .Net method, but solved this problem.
