35 * these, also implement net.exe, at least for "net start" and
36 * "net stop" (should be pretty easy I guess, assuming the rest
37 * of the services API infrastructure works.
39 * o Is supposed to use RPC, not random kludges, to map endpoints.
41 * o Probably name services should be implemented here as well.
43 * o Wine's named pipes (in general) may not interoperate with those of
46 * o There is a looming problem regarding listening on privileged
47 * ports. We will need to be able to coexist with SAMBA, and be able
48 * to function without running winelib code as root. This may
49 * take some doing, including significant reconceptualization of the
50 * role of rpcss.exe in wine.
52 * o Who knows? Whatever rpcss does, we ought to at
53 * least think about doing... but what /does/ it do?
