I like the look of the workspace code Sebastien has been writing and I propose to try it out on samples/calculator-distributed.
In particular I'd like to help Felix who is hitting the common filesystem restriction of the current domain implementation . Let me know if anyone has any concerns. I'll report back with what I learn. There are other modules that rely on distributed support itest/callable-references itest/domain itest/osgi-tuscany/tuscany-3rdparty itest/osgi-tuscay/tuscany-runtime samples/calculator-distributed tools/eclipse/plugins/runtime I'm happy to think about those if the sample/calculator-distributed goes ok.
