Usually InstallShield falls back to using CoCreateInstance to launch
IDriver.exe, so this is a bit unusual. However, if the moniker has been
registered in another process then this would indeed be the problem.

The solution is to do RPC calls to a server process (RPCSS) to keep a global
record of the ROT and then cache bits of it on the client-side. The Irot* calls
mentioned in FIXME's are the future RPC calls. The RPC calls obviously depend on
Dan Hipschman's widl work, but what he's done so far might be sufficient, so
I'll try to write out some sample IDL that I think will be needed for the interface.
